Utilizing Implicit User Feedback to Improve Interactive Video Retrieval
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
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.…”
