Description: This paper (and accompanying MATLAB source code) is a review of the block matching algorithms used for motion estimation in video compression. It implements and compares 7 different types of block matching algorithms that range from the very basic Exhaustive Search to the recent fast adaptive algorithms like Adaptive Rood Pattern Search. The algorithms that are evaluated in this paper are widely accepted by the video compressing community and have been used in implementing various standards, ranging from MPEG1 / H.261 to MPEG4 / H.263. The paper also presents a very brief introduction to the entire flow of video compression.

Description: 本文讲述多媒体转码从H.263到新一代视频编码标准H.264的异构网络转码的新算法研究-In this paper, we investigate and propose efficient methods
for transcoding H.263 video to H.264/AVC standard
by exploiting the new coding features. Specifically, the proposed
methods aim to reduce the computational complexity
while maintaining acceptable video quality for syntax
transcoding and 2 : 1 downsizing transcoding from H.263
to H.264/AVC standard. In a nutshell, the proposed methods
include three components, namely fast intraprediction mode
selection, motion vector reestimation and intermode selection,
and enhanced rate control for H.264AVC transcoding.
The first two components focus on the most computationally
intensive parts of the H.264/AVC standard to speed up
the transcoding process, while the third component aims to
achieve a better video quality by enhancing the rate control
with the side information extracted fromthe precoded video.
The experimental results show that the proposed methods
can reduce the total encoding time by a factor of 6 and suffer
