Screen content has been an important extension of high efficiency video coding widely used in wireless display and screen sharing. Reconstructed screen content images have distortions because of the quantization of transforming coefficients. Hence, this paper proposes an enhanced block-matching and 3D filter (BM3D) to attenuate the distortion by block classification and block segmentation. Experimental...
To satisfy the rapidly increasing demands for high resolution video, the Joint Collaborative Team on Video Coding (JCT-VC) developed a new video coding standard, i.e. High-efficiency Video Coding (HEVC). With the same perceptual video quality as H.264, HEVC can achieve a bit rate reduction of approximately 50%. However, the quad tree structured coding units (CUs) cause high computational complexity...
With the development of 3D video technology, many studies have paid attention to compression efficiency and rate distortion performance. When 3D videos are transmitted over error-prone channels, they may suffer significant quality degradation. In this paper, we combine multiview video coding (MVC) with multiple description coding (MDC) for robust transmission. The proposed scheme can give full consideration...
High efficiency video coding (HEVC) is an emerging video compression standard, developed by the Joint Collaborative Team on Video Coding (JCT-VC). The aim of HEVC standardization effort is to save about 50% bit rate for equal perceptual video quality relative to H.264/AVC. Although HEVC provides greater bit rate saving, it also brings the enormous encoding complexity increase. In this paper, we propose...
In this paper we present a SNR scalable extension design on three-dimensional video compression using High Efficiency Video Coding (3D-HEVC). A multi-loop decoder solution is integrated into the proposed scalable coding serves as the whole framework for the SNR scalable 3D-HEVC. To effectively improve the coding performance, an inter-layer texture prediction is extended into the proposed scalable...
A nonlinear exponential weighted algorithm is proposed for the MAD calculation based on deep research on the proposal of rate control-JVT-H017, as rate control is an important component of video compression technology which plays a great role in stabilizing rate and ensures a good reception quality. In addition, a new judging method of rate control effects is also introduced before representing the...
The Shannon/Nyquist sampling theorem claim that when capturing a signal, one must sample at least two times faster than the signal bandwidth in order to avoid losing information. Nowadays, compressive sensing, as a big idea in signal processing, is a new method to capture and represent compressible signals at a rate significantly below the Nyquist rate. In this paper, compressive sensing is applied...
