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.…”

Forensic of video object removal tamper based on 3D dual-stream network
Published 2021-12-01“…In order to solve the problems of inaccurate temporal detection and location of the object removal tampered video, a video tamper forensics method based on 3D dual-stream network was proposed.Firstly, the spatial rich model (SRM) layer was used to extract the high-frequency information from video frames.Secondly, the improved 3D convolution (C3D) network was used as the feature extractor of the dual-stream network to extract the high-frequency information and low-frequency information from the high-frequency frame and the original video frame respectively.Finally, through compact bilinear pooling (CBP) layer, two sets of different feature vectors were fused into one set of feature vectors for classification prediction.The experimental results demonstrate that the classification accuracy of the proposed method in all video frames has an advantage in SYSU-OBJFORG dataset, which makes the temporal detection and location of object removal tampered video more accurate.…”
