    Reidentification of Persons Using Clothing Features in Real-Life Video by Guodong Zhang, Peilin Jiang, Kazuyuki Matsumoto, Minoru Yoshida, Kenji Kita

    Published 2017-01-01
    “…Person reidentification, which aims to track people across nonoverlapping cameras, is a fundamental task in automated video processing. Moving people often appear differently when viewed from different nonoverlapping cameras because of differences in illumination, pose, and camera properties. …”

    Utilizing Implicit User Feedback to Improve Interactive Video Retrieval by Stefanos Vrochidis, Ioannis Kompatsiaris, Ioannis Patras

    Published 2011-01-01
    “…This paper describes an approach to exploit the implicit user feedback gathered during interactive video retrieval tasks. We propose a framework, where the video is first indexed according to temporal, textual, and visual features and then implicit user feedback analysis is realized using a graph-based methodology. …”

    No-feedback rate control algorithm for Wyner-Ziv video coding by SONG Bin, YANG Ming-ming, QIN Hao, HE Hong

    Published 2011-01-01
    “…To avoid using feedback channel,an encoder rate control algorithm for Wyner-Ziv video coding was proposed.Firstly,using the target frame-rate and the target bit-rate,It could determine the bit allocation for each group-of-picture(GOP).According to the correlation between adjacent frames,the bit budget for a GOP were further allocated to key frame and Wyner-Ziv frames within the GOP by dynamically choosing quantization parameter and quantization matrices.Then,with refinement of correlation-noise model(CNM) parameter,different LDPC(low-density parity-check) check matrices might be chosen for each bitplane to control the encoding bitrate of Wyner-Ziv frame.Experimental results show that the difference between expected target bitrate and actual encoded bitrate is less than 0.57% using the proposed method,and compared with existing algorithm,average PSNR(peak signal-to-noise ratio) of decoded video quality can be increased by 1 dB.In addition,our algorithm slightly increases encoder complexity,and can be used in practice.…”
