High Efficiency Video Coding (HEVC) is the state-of-the-art video coding standard. It adopts
a hierarchical quad-tree-based coding unit (CU) partitioning structure that is flexible in …

In this paper, we propose an efficient compression scheme for focal stack images (FoSIs)
based on a new basis-quadtree representation. In the new basis-quadtree representation …

Existing video steganography puts much emphasis on the design of algorithms such as
mapping rules or distortion functions, thereby ignoring the selection of cover to embed secret …

The affine-motion model is able to capture rotation, zooming, and the deformation of moving
objects, thereby providing a better motion-compensated prediction. However, it is not widely …

This paper presents an advanced screen content coding solution using color table and
index map (cTIM) method. This cTIM scheme is implemented in the range extensions of high …

The state-of-the-art High Efficiency Video Coding (HEVC) standard adopts a hierarchical
coding structure to improve its coding efficiency. This allows for the quantization parameter …

Due to the widely used inter prediction in the current video coding standards, encoding units
in different frames is of temporal dependency in that the rate-distortion optimization (RDO) of …
