AUX Information Assisted HEVC

چکیده
An AUX information assisted HEVC is described in this paper. This new functionality provides a tool for HEVC to determine the quantization parameter of CU based on auxiliary input. In this report, a saliency based auxiliary input is employed as a proof-of-concept. As shown in our subjective tests, the new tool achieves up to 12% bit rate reduction with negligible perceptual quality loss.

A Large-capacity Information Hiding Method for HEVC Video
A large-capacity information hiding algorithm for HEVC is proposed. We modify the intra prediction modes in 4x4 luminance blocks to embed secret information. According to the probability distribution of the statistical optimal prediction mode and suboptimal prediction mode, we are establishing a mapping relationship between prediction modes and secret information. Modifying the intra prediction...
متن کاملFast 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...
