Description: 改进后的算法大大减少了对于那些运动矢量为零的块的搜索冗余，同时对于运动比较剧烈的块直接进入大范围搜索。这样即提高了搜索效率，又不会使搜索结果陷入局部最优。-improved algorithm greatly reduced for those zero motion vector search block redundancy, Meanwhile, more intense campaign of direct access to block large-scale search. That would improve the efficiency of search, the search results will not find the global optimum.

Description: Buddy（伙伴）算法每次分配包含一个或者多个物理页面的内存块，页面以2的次幂的内存块来分配。首先搜寻满足请求大小的页面，它从满足当前申请大小的Buddy数据结构的m_ freePages域着手沿链来搜索空闲页面。如果没有这样请求大小的空闲页面，则它搜索两倍于请求大小的内存块。这个过程一直将持续到所有的Buddy 被搜索完或找到满足要求的内存块为。如果找到的页面块大于请求的块则对其进行分割以使其大小与请求块匹配。由于块大小都是2的次幂所以分割过程十分简单：空闲块（低地址）被连进相应大小的队列而这个页面块被分配给调用者。 释放时，先检查该块的伙伴的使用情况，如果没有被使用，则合并这对Buddy，再检查该两倍大小的块的Buddy，一直持续到合并后的块没有Buddy为止，并将之链到该大小的freepage队列中。-Buddy (partners) each allocation algorithm contains a number of physical pages or blocks of memory, two pages to the Powers of the block of memory to allocate. First of all search requests to meet the size of pages, from the application to meet the current size of the data structure Buddy 8 freePages domain proceed along the chain to search leisure pages. If no such request size spare pages, which then search request twice the size of a memory block. This process has to continue until all the Buddy Search End or were found to meet the requirements for the memory block. If found in the pages block greater than the requested block is divided in its size and make it the request block matching. As pieces are the two Powers So segmentation process is very simple : free block (low-address) was e

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.
