چکیده

Baptized “LAR Video”, method proposed in this paper describes a new lossless video coding algorithm with advanced semantic scalability. Motion estimation and compensation steps are first achieved to produce the well known displaced frame difference (DFD). The basic idea is to apply on this residual error a pyramidal decomposition based on an efficient scalable image compression technique, named LAR-APP. Resulting from a progressive data broadcasting, image-sequence can be scalably rebuilt in the decoder at different spatial resolution level. The given experimental results show that the proposed solution, in addition to the scalability, achieves good compression performances.

Extending JPEG-LS for low-complexity scalable video coding

JPEG-LS, the well-known international standard for lossless and near-lossless image compression, was originally designed for non-scalable applications. In this paper we propose a scalable modification of JPEG-LS and compare it with the leading image and video coding standards JPEG2000 and H.264/SVC intra for low-complexity constraints of some wireless video applications including graphics.

Compressed Domain Scene Change Detection Based on Transform Units Distribution in High Efficiency Video Coding Standard

Scene change detection plays an important role in a number of video applications, including video indexing, searching, browsing, semantic features extraction, and, in general, pre-processing and post-processing operations. Several scene change detection methods have been proposed in different coding standards. Most of them use fixed thresholds for the similarity metrics to determine if there wa...

Fast Intra Mode Decision for Depth Map coding in 3D-HEVC Standard

three dimensional- high efficiency video coding (3D-HEVC) is the expanded version of the latest video compression standard, namely high efficiency video coding (HEVC), which is used to compress 3D videos. 3D videos include texture video and depth map. Since the statistical characteristics of depth maps are different from those of texture videos, new tools have been added to the HEVC standard fo...

Quality constraint and rate-distortion optimization for predictive image coders

Next generations of image and video coding methods should of course be efficient in terms of compression, but also propose advanced functionalities. Among these functionalities such as scalability, lossy and lossless coding, data protection, Rate Distortion Optimization (RDO) and Rate Control (RC) are key issues. RDO aims at optimizing compression performances, while RC mechanism enables to exa...
