  • Dimensionality reduction via locally reconstructive patch alignment
    • Abstract: Yi Chen, Jun Yin, Jie Zhu et al. Based on the local patch concept, we proposed locally reconstructive patch alignment (LRPA) for dimensionality reduction. For each patch, LRPA aims to find the low-dimensional subspace in which the reconstruction error of the within-class nearest neighbors is minimized and the reconstruction error o ... [Opt.

  • Analysis of input pump pulse energy optimization for maximum four-wave mixing conversion efficiency in semiconductor optical amplifier
    • Abstract: S. Rasoul Hosseini, Mohammad Razaghi, and Narottam K. Das We configure the input pump pulse energy of semiconductor optical amplifiers (SOAs) to maximize the four-wave mixing (FWM) conversion efficiency. We simulate the propagation of optical waves in the SOA using the nonlinear propagation equation, taking into account the gain spectrum dynamics, gain sat ... [Opt.

  • Misalignment-robust, edge-based image fusion method
    • Abstract: Cai Xi and Zhao Wei We propose an image fusion method robust to misaligned source images based on their multiscale edge representations. Significant long edge curves at the second scale are selected to decide edge locations at each scale for the multiscale edge representations of source images. Then, processes are only ... [Opt.

  • Joint data-hiding and rate-distortion optimization for H.264/AVC videos
    • Abstract: Yih-Chuan Lin and Jung-Hong Li We address video data-hiding on the context-adaptive variable-length coding domain of the H.264/AVC standard. It is challenging to maintain a minimum variation of rate-distortion performance when hiding data in compressed videos by slightly modifying one or more transform coefficients of prediction ... [Opt.

  • Optical computing with semiconductor optical amplifiers
    • Abstract: Rekha Mehra, Shikha Jaiswal, and Hemant Kumar Dixit Increasing communication traffic and plans to increase various services may cause a serious problem towards the power consumption of network equipment. One of the causes of large power consumption in the present network is the multiplexing scheme, such as wavelength division multiplexing (WDM) and e ... [Opt.

  • One image denoizing model with local constraints on dyadic regions
    • Abstract: Zhang Tao and Gao Qiuli Total variation minimizing methods have known great success in image denoizing. Although edge sharpness is well preserved by these methods, important information like textures or small details is often removed in the process of denoizing. We propose a novel denoizing model which better preserves fin ... [Opt. Eng. 51, 077006 (2012)] published Thu Jul 26, 2012.

We describe an ultra-thin and low-power optical interconnect module for mobile electronic devices such as mobile phones and notebooks. The module was fabricated by directly packaging optic and electronic components onto a thin and flexible optical printed circuit board having a size of 70 x 8 x 0.25 ... [Opt.

  • Noise sources in imaging static Fourier transform spectrometers
    • Abstract: Yann Ferrec, Noura Ayari-Matallah, Pierre Chavel et al. Imaging static Fourier transform spectrometers are well-adapted instruments for remote sensing. However, the path from the raw images to the spectral images is quite long, thus multiplying the potential noise sources. In this article, we propose to review these perturbation sources. We first recall ... [Opt. Eng. 51, 111716 (2012)] published Thu Jul 19, 2012.
