  • Deep Cross-Modal Correlation Learning for Audio and Lyrics in Music
           Retrieval
    • Abstract: Yi Yu, Suhua Tang, Francisco Raposo, Lei Chen

      Deep cross-modal learning has successfully demonstrated excellent performance in cross-modal multimedia retrieval, with the aim of learning joint representations between different data modalities. Unfortunately, little research focuses on cross-modal correlation learning where temporal structures of different data modalities, such as audio and lyrics, should be taken into account. Stemming from the characteristic of temporal structures of music in nature, we are motivated to learn the deep sequential correlation between audio and lyrics. In this work, we propose a deep cross-modal correlation learning architecture involving two-branch deep neural networks for audio modality and text modality (lyrics). Data in different modalities are converted to the same canonical space where intermodal canonical correlation analysis is utilized as an objective function to calculate the similarity of temporal structures.

  • Expression Robust 3D Facial Landmarking via Progressive Coarse-to-Fine
           Tuning
    • Abstract: Jia Sun, Di Huang, Yunhong Wang, Liming Chen

      Facial landmarking is a fundamental task in automatic machine-based face analysis. The majority of existing techniques for such a problem are based on 2D images; however, they suffer from illumination and pose variations that may largely degrade landmarking performance. The emergence of 3D data theoretically provides an alternative to overcome these weaknesses in the 2D domain. This article proposes a novel approach to 3D facial landmarking, which combines both the advantages of feature-based methods as well as model-based ones in a progressive three-stage coarse-to-fine manner (initial, intermediate, and fine stages). For the initial stage, a few fiducial landmarks (i.e., the nose tip and two inner eye corners) are robustly detected through curvature analysis, and these points are further exploited to initialize the subsequent stage.

  • Photorealistic Face Completion with Semantic Parsing and Face
           Identity-Preserving Features
    • Abstract: Ruijun Ma, Haifeng Hu, Weixuan Wang, Jia Xu, Zhengming Li

      Tremendous progress on deep learning has shown exciting potential for a variety of face completion tasks. However, most learning-based methods are limited to handle general or structure specified face images (e.g., well-aligned faces). In this article, we propose a novel face completion algorithm, called Learning and Preserving Face Completion Network (LP-FCN), which simultaneously parses face images and extracts face identity-preserving (FIP) features. By tackling these two tasks in a mutually boosting way, the LP-FCN can guide an identity preserving inference and ensure pixel faithfulness of completed faces. In addition, we adopt a global discriminator and a local discriminator to distinguish real images from synthesized ones.

    • Abstract: Jakub Lokoč, Gregor Kovalčík, Bernd Münzer, Klaus Schöffmann, Werner Bailer, Ralph Gasser, Stefanos Vrochidis, Phuong Anh Nguyen, Sitapa Rujikietgumjorn, Kai Uwe Barthel

      This work summarizes the findings of the 7th iteration of the Video Browser Showdown (VBS) competition organized as a workshop at the 24th International Conference on Multimedia Modeling in Bangkok. The competition focuses on video retrieval scenarios in which the searched scenes were either previously observed or described by another person (i.e., an example shot is not available). During the event, nine teams competed with their video retrieval tools in providing access to a shared video collection with 600 hours of video content. Evaluation objectives, rules, scoring, tasks, and all participating tools are described in the article. In addition, we provide some insights into how the different teams interacted with their video browsers, which was made possible by a novel interaction logging mechanism introduced for this iteration of the VBS.

  • Efficient QoE-Aware Scheme for Video Quality Switching Operations in
           Dynamic Adaptive Streaming
    • Abstract: Iheanyi Irondi, Qi Wang, Christos Grecos, Jose M. Alcaraz Calero, Pablo Casaseca-De-La-Higuera

      Dynamic Adaptive Streaming over HTTP (DASH) is a popular over-the-top video content distribution technique that adapts the streaming session according to the user's network condition typically in terms of downlink bandwidth. This video quality adaptation can be achieved by scaling the frame quality, spatial resolution or frame rate. Despite the flexibility on the video quality scaling methods, each of these quality scaling dimensions has varying effects on the Quality of Experience (QoE) for end users. Furthermore, in video streaming, the changes in motion over time along with the scaling method employed have an influence on QoE, hence the need to carefully tailor scaling methods to suit streaming applications and content type.

  • HTTP/2-based Frame Discarding for Low-Latency Adaptive Video Streaming
    • Abstract: Mariem Ben Yahia, Yannick Le Louedec, Gwendal Simon, Loutfi Nuaymi, Xavier Corbillon

      In this article, we propose video delivery schemes insuring around 1s delivery latency with Dynamic Adaptive Streaming over HTTP (DASH), which is a standard version of HTTP Live Streaming (HLS), so as to benefit from the video representation switching between successive video segments. We also propose HTTP/2-based algorithms to apply video frame discarding policies inside a video segment when a selected DASH representation does not match with the available network resources. The current solutions with small buffer suffer from rebuffering events. Rebuffering not only impacts the Quality of Experience (QoE) but also increases the delivery delay between the displayed and the original video streams.

  • CM-GANs: Cross-modal Generative Adversarial Networks for Common
           Representation Learning
    • Abstract: Yuxin Peng, Jinwei Qi

      It is known that the inconsistent distributions and representations of different modalities, such as image and text, cause the heterogeneity gap, which makes it very challenging to correlate heterogeneous data and measure their similarities. Recently, generative adversarial networks (GANs) have been proposed and have shown their strong ability to model data distribution and learn discriminative representation. It has also been shown that adversarial learning can be fully exploited to learn discriminative common representations for bridging the heterogeneity gap. Inspired by this, we aim to effectively correlate large-scale heterogeneous data of different modalities with the power of GANs to model cross-modal joint distribution.

  • Modality-Invariant Image-Text Embedding for Image-Sentence Matching
    • Abstract: Ruoyu Liu, Yao Zhao, Shikui Wei, Liang Zheng, Yi Yang

      Performing direct matching among different modalities (like image and text) can benefit many tasks in computer vision, multimedia, information retrieval, and information fusion. Most of existing works focus on class-level image-text matching, called cross-modal retrieval, which attempts to propose a uniform model for matching images with all types of texts, for example, tags, sentences, and articles (long texts). Although cross-model retrieval alleviates the heterogeneous gap among visual and textual information, it can provide only a rough correspondence between two modalities. In this article, we propose a more precise image-text embedding method, image-sentence matching, which can provide heterogeneous matching in the instance level.

  • Visual Content Recognition by Exploiting Semantic Feature Map with
           Attention and Multi-task Learning
    • Abstract: Rui-Wei Zhao, Qi Zhang, Zuxuan Wu, Jianguo Li, Yu-Gang Jiang

      Recent studies have shown that spatial relationships among objects are very important for visual recognition, since they can provide rich clues on object contexts within the images. In this article, we introduce a novel method to learn the Semantic Feature Map (SFM) with attention-based deep neural networks for image and video classification in an end-to-end manner, aiming to explicitly model the spatial object contexts within the images. In particular, we explicitly apply the designed gate units to the extracted object features for important objects selection and noise removal. These selected object features are then organized into the proposed SFM, which is a compact and discriminative representation with the spatial information among objects preserved.

  • Deep Learning–Based Multimedia Analytics: A Review
    • Abstract: Wei Zhang, Ting Yao, Shiai Zhu, Abdulmotaleb El Saddik

      The multimedia community has witnessed the rise of deep learning–based techniques in analyzing multimedia content more effectively. In the past decade, the convergence of deep-learning and multimedia analytics has boosted the performance of several traditional tasks, such as classification, detection, and regression, and has also fundamentally changed the landscape of several relatively new areas, such as semantic segmentation, captioning, and content generation. This article aims to review the development path of major tasks in multimedia analytics and take a look into future directions. We start by summarizing the fundamental deep techniques related to multimedia analytics, especially in the visual domain, and then review representative high-level tasks powered by recent advances.

  • Convolutional Attention Networks for Scene Text Recognition
    • Abstract: Hongtao Xie, Shancheng Fang, Zheng-Jun Zha, Yating Yang, Yan Li, Yongdong Zhang

      In this article, we present Convoluitional Attention Networks (CAN) for unconstrained scene text recognition. Recent dominant approaches for scene text recognition are mainly based on Convolutional Neural Networks (CNN) and Recurrent Neural Networks (RNN), where the CNN encodes images and the RNN generates character sequences. Our CAN is different from these methods; our CAN is completely built on CNN and includes an attention mechanism. The distinctive characteristics of our method include (i) CAN follows encoder-decoder architecture, in which the encoder is a deep two-dimensional CNN and the decoder is a one-dimensional CNN; (ii) the attention mechanism is applied in every convolutional layer of the decoder, and we propose a novel spatial attention method using average pooling; and (iii) position embeddings are equipped in both a spatial encoder and a sequence decoder to give our networks a sense of location.

  • Structure-Aware Deep Learning for Product Image Classification
    • Abstract: Zhineng Chen, Shanshan Ai, Caiyan Jia

      Automatic product image classification is a task of crucial importance with respect to the management of online retailers. Motivated by recent advancements of deep Convolutional Neural Networks (CNN) on image classification, in this work we revisit the problem in the context of product images with the existence of a predefined categorical hierarchy and attributes, aiming to leverage the hierarchy and attributes to improve classification accuracy. With these structure-aware clues, we argue that more advanced deep models could be developed beyond the flat one-versus-all classification performed by conventional CNNs. To this end, novel efforts of this work include a salient-sensitive CNN that gazes into the product foreground by inserting a dedicated spatial attention module; a multiclass regression-based refinement that is expected to predict more accurately by merging prediction scores from multiple preceding CNNs, each corresponding to a distinct classifier in the hierarchy; and a multitask deep learning architecture that effectively explores ...

  • Deep Patch Representations with Shared Codebook for Scene Classification
    • Abstract: Shuqiang Jiang, Gongwei Chen, Xinhang Song, Linhu Liu

      Scene classification is a challenging problem. Compared with object images, scene images are more abstract, as they are composed of objects. Object and scene images have different characteristics with different scales and composition structures. How to effectively integrate the local mid-level semantic representations including both object and scene concepts needs to be investigated, which is an important aspect for scene classification. In this article, the idea of a sharing codebook is introduced by organically integrating deep learning, concept feature, and local feature encoding techniques. More specifically, the shared local feature codebook is generated from the combined ImageNet1K and Places365 concepts (Mixed1365) using convolutional neural networks.

  • Cross-Modality Feature Learning via Convolutional Autoencoder
    • Abstract: Xueliang Liu, Meng Wang, Zheng-Jun Zha, Richang Hong

      Learning robust and representative features across multiple modalities has been a fundamental problem in machine learning and multimedia fields. In this article, we propose a novel MUltimodal Convolutional AutoEncoder (MUCAE) approach to learn representative features from visual and textual modalities. For each modality, we integrate the convolutional operation into an autoencoder framework to learn a joint representation from the original image and text content. We optimize the convolutional autoencoders of different modalities jointly by exploiting the correlation between the hidden representations from the convolutional autoencoders, in particular by minimizing both the reconstructing error of each modality and the correlation divergence between the hidden feature of different modalities.

  • Dense 3D-Convolutional Neural Network for Person Re-Identification in
           Videos
    • Abstract: Jiawei Liu, Zheng-Jun Zha, Xuejin Chen, Zilei Wang, Yongdong Zhang

      Person re-identification aims at identifying a certain pedestrian across non-overlapping multi-camera networks in different time and places. Existing person re-identification approaches mainly focus on matching pedestrians on images; however, little attention has been paid to re-identify pedestrians in videos. Compared to images, video clips contain motion patterns of pedestrians, which is crucial to person re-identification. Moreover, consecutive video frames present pedestrian appearance with different body poses and from different viewpoints, providing valuable information toward addressing the challenge of pose variation, occlusion, and viewpoint change, and so on. In this article, we propose a Dense 3D-Convolutional Network (D3DNet) to jointly learn spatio-temporal and appearance representation for person re-identification in videos.

  • Deep Semantic Mapping for Heterogeneous Multimedia Transfer Learning Using
           Co-Occurrence Data
    • Abstract: Liang Zhao, Zhikui Chen, Laurence T. Yang, M. Jamal Deen, Z. Jane Wang

      Transfer learning, which focuses on finding a favorable representation for instances of different domains based on auxiliary data, can mitigate the divergence between domains through knowledge transfer. Recently, increasing efforts on transfer learning have employed deep neural networks (DNN) to learn more robust and higher level feature representations to better tackle cross-media disparities. However, only a few articles consider the correction and semantic matching between multi-layer heterogeneous domain networks. In this article, we propose a deep semantic mapping model for heterogeneous multimedia transfer learning (DHTL) using co-occurrence data. More specifically, we integrate the DNN with canonical correlation analysis (CCA) to derive a deep correlation subspace as the joint semantic representation for associating data across different domains.

  • Special Section on Multimodal Understanding of Social, Affective, and
           Subjective Attributes
    • Abstract: Xavier Alameda-Pineda, Miriam Redi, Mohammad Soleymani, Nicu Sebe, Shih-Fu Chang, Samuel Gosling

      Multimedia scientists have largely focused their research on the recognition of tangible properties of data such as objects and scenes. Recently, the field has started evolving toward the modeling of more complex properties. For example, the understanding of social, affective, and subjective attributes of visual data has attracted the attention of many research teams at the crossroads of computer vision, multimedia, and social sciences. These intangible attributes include, for example, visual beauty, video popularity, or user behavior. Multiple, diverse challenges arise when modeling such properties from multimedia data. The sections concern technical aspects such as reliable groundtruth collection, the effective learning of subjective properties, or the impact of context in subjective perception; see Refs.

  • Virtual Portraitist: An Intelligent Tool for Taking Well-Posed Selfies
    • Abstract: Chuan-Shen Hu, Yi-Tsung Hsieh, Hsiao-Wei Lin, Mei-Chen Yeh

      Smart photography carries the promise of quality improvement and functionality extension in making aesthetically appealing pictures. In this article, we focus on self-portrait photographs and introduce new methods that guide a user in how to best pose while taking a selfie. While most of the current solutions use a post processing procedure to beautify a picture, the developed tool enables a novel function of recommending a good look before the photo is captured. Given an input face image, the tool automatically estimates the pose-based aesthetic score, finds the most attractive angle of the face, and suggests how the pose should be adjusted.

  • Modeling Dyadic and Group Impressions with Intermodal and Interperson
           Features
    • Abstract: Shogo Okada, Laurent Son Nguyen, Oya Aran, Daniel Gatica-Perez

      This article proposes a novel feature-extraction framework for inferring impression personality traits, emergent leadership skills, communicative competence, and hiring decisions. The proposed framework extracts multimodal features, describing each participant’s nonverbal activities. It captures intermodal and interperson relationships in interactions and captures how the target interactor generates nonverbal behavior when other interactors also generate nonverbal behavior. The intermodal and interperson patterns are identified as frequent co-occurring events based on clustering from multimodal sequences. The proposed framework is applied to the SONVB corpus, which is an audiovisual dataset collected from dyadic job interviews, and the ELEA audiovisual data corpus, which is a dataset collected from group meetings.

  • Personalized Emotion Recognition by Personality-Aware High-Order Learning
           of Physiological Signals
    • Abstract: Sicheng Zhao, Amir Gholaminejad, Guiguang Ding, Yue Gao, Jungong Han, Kurt Keutzer

      Due to the subjective responses of different subjects to physical stimuli, emotion recognition methodologies from physiological signals are increasingly becoming personalized. Existing works mainly focused on modeling the involved physiological corpus of each subject, without considering the psychological factors, such as interest and personality. The latent correlation among different subjects has also been rarely examined. In this article, we propose to investigate the influence of personality on emotional behavior in a hypergraph learning framework. Assuming that each vertex is a compound tuple (subject, stimuli), multi-modal hypergraphs can be constructed based on the personality correlation among different subjects and on the physiological correlation among corresponding stimuli.

  • Reconstructing 3D Face Models by Incremental Aggregation and Refinement of
           Depth Frames
    • Abstract: Pietro Pala, Stefano Berretti

      Face recognition from two-dimensional (2D) still images and videos is quite successful even with “in the wild” conditions. Instead, less consolidated results are available for the cases in which face data come from non-conventional cameras, such as infrared or depth. In this article, we investigate this latter scenario assuming that a low-resolution depth camera is used to perform face recognition in an uncooperative context. To this end, we propose, first, to automatically select a set of frames from the depth sequence of the camera because they provide a good view of the face in terms of pose and distance. Then, we design a progressive refinement approach to reconstruct a higher-resolution model from the selected low-resolution frames.

  • Orchestrating Caching, Transcoding and Request Routing for Adaptive Video
           Streaming Over ICN
    • Abstract: Han Hu, Yichao Jin, Yonggang Wen, Cedric Westphal

      Information-centric networking (ICN) has been touted as a revolutionary solution for the future of the Internet, which will be dominated by video traffic. This work investigates the challenge of distributing video content of adaptive bitrate (ABR) over ICN. In particular, we use the in-network caching capability of ICN routers to serve users; in addition, with the help of named function, we enable ICN routers to transcode videos to lower-bitrate versions to improve the cache hit ratio. Mathematically, we formulate this design challenge into a constrained optimization problem, which aims to maximize the cache hit ratio for service providers and minimize the service delay for endusers.

  • Discovering Latent Topics by Gaussian Latent Dirichlet Allocation and
           Spectral Clustering
    • Abstract: Bo Yuan, Xinbo Gao, Zhenxing Niu, Qi Tian

      Today, diversifying the retrieval results of a certain query will improve customers’ search efficiency. Showing the multiple aspects of information provides users an overview of the object, which helps them fast target their demands. To discover aspects, research focuses on generating image clusters from initially retrieved results. As an effective approach, latent Dirichlet allocation (LDA) has been proved to have good performance on discovering high-level topics. However, traditional LDA is designed to process textual words, and it needs the input as discrete data. When we apply this algorithm to process continuous visual images, a common solution is to quantize the continuous features into discrete form by a bag-of-visual-words algorithm.

  • Image Captioning With Visual-Semantic Double Attention
    • Abstract: Chen He, Haifeng Hu

      In this article, we propose a novel Visual-Semantic Double Attention (VSDA) model for image captioning. In our approach, VSDA consists of two parts: a modified visual attention model is used to extract sub-region image features, then a new SEmantic Attention (SEA) model is proposed to distill semantic features. Traditional attribute-based models always neglect the distinctive importance of each attribute word and fuse all of them into recurrent neural networks, resulting in abundant irrelevant semantic features. In contrast, at each timestep, our model selects the most relevant word that aligns with current context. In other words, the real power of VSDA lies in the ability of not only leveraging semantic features but also eliminating the influence of irrelevant attribute words to make the semantic guidance more precise.
