An adaptive color transform approach and its application in 4∶4∶4 video coding
نویسندگان
چکیده
We propose to extend block-based video-coding by an adaptive color space transform. The presented technique enables an encoder to switch between several given color space representations with the objective to maximize the overall ratedistortion gain. Simulations based on the current draft of the H.264/MPEG4-AVC 4:4:4 extensions demonstrate that our technique provides a rate-distortion performance equal or better than that obtained when using any of the individual color spaces only.

Wyner-Ziv Bayer-pattern video coding
This thesis addresses the problem of Bayer-pattern video communications using Wyner-Ziv video coding (WZVC). It is studied how to take advantage of the low encoding complexity and the inherent error resiliency of WZVC for video compression and transmission. Moreover, it is investigated how to optimize the coding process specifically for Bayer-pattern video in order to improve the coding efficie...
متن کاملAn Efficient Compound Video Compression by Exploiting Spatial Correlation
In the past, JBIG technique produced strong anisotropic features. But JBIG has inefficient on compress. To solve the problem, this paper proposes a novel coding scheme based on the H.264 intra-frame coding. The H.264 contains two steps to compress the video. The first is residual scalar quantization (RSQ) mode. It directly quantized and entropy coded. In the entropy coding part, quantized resid...

This paper addresses the issue of cell loss and its consequent effect on video quality in a packet video system, and examines possible compensative measures. In the system's enconder, adaptive spectral separation is used to develop a two-layer coding scheme comprising a high priority layer to carry essential video data and a low priority layer with data to enhance the video image. A two-step er...
متن کاملVideo Coding Based on Shape-Adaptive All Phase Biorthogonal Transform and MPEG-4
—This paper proposes an efficient video coding algorithm based on shape-adaptive all phase biorthogonal transform (SA-APBT) and MPEG-4. Firstly, the input video sequence is segmented into many arbitrarily shaped video objects. Then the motion, shape and texture of all video objects are encoded in accordance with priority. Shape coding uses context-based arithmetic encoding (CAE). SA-APBT and u...
