  • A Network-Based Virtual Reality Simulation Training Approach for
           Orthopedic Surgery
    • Abstract: J. Cecil, Avinash Gupta, M. Pirela-Cruz, Parmesh Ramanathan

      The focus of this article is on the adoption of immersive and haptic simulators for training of medical residents in a surgical process called Less Invasive Stabilization System (LISS) plating surgery. LISS surgery is an orthopedic surgical procedure to treat fractures of the femur bone. Development of such simulators is a complex task which involves multiple systems, technologies, and human experts. Emerging Next Generation Internet technologies were used to develop the standalone on-line haptic-based simulator accessible to the students 24/7. A standalone immersive surgical simulator was also developed using HTC Vive. Expert surgeons played an important role in developing the simulator system; use cases of the target surgical processes were built using a modeling language called the engineering Enterprise Modeling Language (eEML).

  • ORL-SDN: Online Reinforcement Learning for SDN-Enabled HTTP Adaptive
           Streaming
    • Abstract: Abdelhak Bentaleb, Ali C. Begen, Roger Zimmermann

      In designing an HTTP adaptive streaming (HAS) system, the bitrate adaptation scheme in the player is a key component to ensure a good quality of experience (QoE) for viewers. We propose a new online reinforcement learning optimization framework, called ORL-SDN, targeting HAS players running in a software-defined networking (SDN) environment. We leverage SDN to facilitate the orchestration of the adaptation schemes for a set of HAS players. To reach a good level of QoE fairness in a large population of players, we cluster them based on a perceptual quality index. We formulate the adaptation process as a Partially Observable Markov Decision Process and solve the per-cluster optimization problem using an online Q-learning technique that leverages model predictive control and parallelism via aggregation to avoid a per-cluster suboptimal selection and to accelerate the convergence to an optimum.

  • Learning Multiple Kernel Metrics for Iterative Person Re-Identification
    • Abstract: Husheng Dong, Ping Lu, Chunping Liu, Yi Ji, Shengrong Gong

      In person re-identification most metric learning methods learn from training data only once, and then they are deployed for testing. Although impressive performance has been achieved, the discriminative information from successfully identified test samples are ignored. In this work, we present a novel re-identification framework termed Iterative Multiple Kernel Metric Learning (IMKML). Specifically, there are two main modules in IMKML. In the first module, multiple metrics are learned via a new derived Kernel Marginal Nullspace Learning (KMNL) algorithm. Taking advantage of learning a discriminative nullspace from neighborhood manifold, KMNL can well tackle the Small Sample Size (SSS) problem in re-identification distance metric learning.

  • Aesthetic Highlight Detection in Movies Based on Synchronization of
           Spectators’ Reactions
    • Abstract: Michal Muszynski, Theodoros Kostoulas, Patrizia Lombardo, Thierry Pun, Guillaume Chanel

      Detection of aesthetic highlights is a challenge for understanding the affective processes taking place during movie watching. In this article, we study spectators’ responses to movie aesthetic stimuli in a social context. Moreover, we look for uncovering the emotional component of aesthetic highlights in movies. Our assumption is that synchronized spectators’ physiological and behavioral reactions occur during these highlights because: (i) aesthetic choices of filmmakers are made to elicit specific emotional reactions (e.g., special effects, empathy, and compassion toward a character) and (ii) watching a movie together causes spectators’ affective reactions to be synchronized through emotional contagion. We compare different approaches to estimation of synchronization among multiple spectators’ signals, such as pairwise, group, and overall synchronization measures to detect aesthetic highlights in movies.

  • Automatic Data Augmentation from Massive Web Images for Deep Visual
           Recognition
    • Abstract: Yalong Bai, Kuiyuan Yang, Tao Mei, Wei-Ying Ma, Tiejun Zhao

      Large-scale image datasets and deep convolutional neural networks (DCNNs) are the two primary driving forces for the rapid progress in generic object recognition tasks in recent years. While lots of network architectures have been continuously designed to pursue lower error rates, few efforts are devoted to enlarging existing datasets due to high labeling costs and unfair comparison issues. In this article, we aim to achieve lower error rates by augmenting existing datasets in an automatic manner. Our method leverages both the web and DCNN, where the web provides massive images with rich contextual information, and DCNN replaces humans to automatically label images under the guidance of web contextual information.

  • User-Click-Data-Based Fine-Grained Image Recognition via Weakly Supervised
           Metric Learning
    • Abstract: Min Tan, Jun Yu, Zhou Yu, Fei Gao, Yong Rui, Dacheng Tao

      We present a novel fine-grained image recognition framework using user click data, which can bridge the semantic gap in distinguishing categories that are similar in visual. As query set in click data is usually large-scale and redundant, we first propose a click-feature-based query-merging approach to merge queries with similar semantics and construct a compact click feature. Afterward, we utilize this compact click feature and convolutional neural network (CNN)-based deep visual feature to jointly represent an image. Finally, with the combined feature, we employ the metriclearning-based template-matching scheme for efficient recognition. Considering the heavy noise in the training data, we introduce a reliability variable to characterize the image reliability, and propose a weakly-supervised metric and template leaning with smooth assumption and click prior (WMTLSC) method to jointly learn the distance metric, object templates, and image reliability.

  • Efficient Video Encoding for Automatic Video Analysis in Distributed
           Wireless Surveillance Systems
    • Abstract: Lingchao Kong, Rui Dai

      In many distributed wireless surveillance applications, compressed videos are used for performing automatic video analysis tasks. The accuracy of object detection, which is essential for various video analysis tasks, can be reduced due to video quality degradation caused by lossy compression. This article introduces a video encoding framework with the objective of boosting the accuracy of object detection for wireless surveillance applications. The proposed video encoding framework is based on systematic investigation of the effects of lossy compression on object detection. It has been found that current standardized video encoding schemes cause temporal domain fluctuation for encoded blocks in stable background areas and spatial texture degradation for encoded blocks in dynamic foreground areas of a raw video, both of which degrade the accuracy of object detection.

  • Image Captioning with Affective Guiding and Selective Attention
    • Abstract: Anqi Wang, Haifeng Hu, Liang Yang

      Image captioning is an increasingly important problem associated with artificial intelligence, computer vision, and natural language processing. Recent works revealed that it is possible for a machine to generate meaningful and accurate sentences for images. However, most existing methods ignore latent emotional information in an image. In this article, we propose a novel image captioning model with Affective Guiding and Selective Attention Mechanism named AG-SAM. In our method, we aim to bridge the affective gap between image captioning and the emotional response elicited by the image. First, we introduce affective components that capture higher-level concepts encoded in images into AG-SAM. Hence, our language model can be adapted to generate sentences that are more passionate and emotive.

  • Soundscape of an Archaeological Site Recreated with Audio Augmented
           Reality
    • Abstract: Marjan Sikora, Mladen Russo, Jurica Đerek, Ante Jurčević

      This article investigates the use of an audio augmented reality (AAR) system to recreate the soundscape of a medieval archaeological site. The aim of our work was to explore whether it is possible to enhance a tourist's archaeological experience, which is often derived from only scarce remains. We developed a smartphone-based AAR system, which uses location and orientation sensors to synthesize the soundscape of a site and plays it to the user via headphones. We recreated the ancient soundscape of a medieval archaeological site in Croatia and tested it in situ on two groups of participants using the soundwalk method. One test group performed the soundwalk while listening to the recreated soundscape using the AAR system, while the second control group did not use the AAR equipment.

  • Properties and Design of Variable-to-Variable Length Codes
    • Abstract: Heiner Kirchhoffer, Detlev Marpe, Heiko Schwarz, Thomas Wiegand

      For the entropy coding of independent and identically distributed (i.i.d.) binary sources, variable-to-variable length (V2V) codes are an interesting alternative to arithmetic coding. Such a V2V code translates variable length words of the source into variable length code words by employing two prefix-free codes. In this article, several properties of V2V codes are studied, and new concepts are developed. In particular, it is shown that the redundancy of a V2V code cannot be zero for a binary i.i.d. source {X} with 0 < pX(1) < 0.5. Furthermore, the concept of prime and composite V2V codes is proposed, and it is shown why composite V2V codes can be disregarded in the search for particular classes of minimum redundancy codes.

  • A Survey on Content-Aware Image and Video Retargeting
    • Abstract: Johannes Kiess, Stephan Kopf, Benjamin Guthier, Wolfgang Effelsberg

      This survey introduces the current state of the art in image and video retargeting and describes important ideas and technologies that have influenced the recent work. Retargeting is the process of adapting an image or video from one screen resolution to another to fit different displays, for example, when watching a wide screen movie on a normal television screen or a mobile device. As there has been considerable work done in this field already, this survey provides an overview of the techniques. It is meant to be a starting point for new research in the field.
