Information hiding refers to the process of inserting information into a host to serve specific
purpose (s). In this paper, information hiding methods in the H. 264/AVC compressed video …

In region-of-interest (ROI)-based video coding, ROI parts of the frame are encoded with
higher quality than non-ROI parts. At low bit rates, such encoding may produce attention …

In this paper, a Rate-GOP based frame level rate control scheme is proposed for High
Efficiency Video Coding (HEVC). The proposed scheme is developed with the consideration …

A system and method for encoding multimedia video is described. As video is encoded a
quantization parameter is selected for each macroblock. As described herein, the …

This paper presents a Quantization Parameter (QP) refinement algorithm used in Rate-
Distortion Optimization (RDO) process to improve the coding efficiency for High Efficiency …

In this paper, we present a method for performing rate-distortion optimization (RDO) using a
perceptual visual quality metric, the structural similarity index (SSIM), as the target of …

The field of video coding has been exploring the compact representation of video data,
where perceptual redundancies in addition to signal redundancies are removed for higher …

An encoder and method for encoding data in a scalable data compression format are
described. In particular, process for encoding spatially scalable video are described in which …

Apparatus and Method for parallel digital picture encoding are disclosed. A digital picture is
partitioned into two or more vertical sections. An encoder unit is selected to serve as a …

There are provided a method and apparatus for adaptive weight selection for motion
compensated prediction. The apparatus includes an encoder for encoding a picture by …
