本章将对MPEG4及H.264的实现细节进行讲解和比对. Motion Estimation 衡量运动估计的好坏有三种函数(第228页):MSE,MAE和SAE,其中由于SAE运算速度最快所以采用的最多. 匹配块时用的搜索方法也有很多,最基本的方法是全局搜索(Full search),但是为了加快编码速度,也会采用一些近似最优的方法,例如一些快速搜索方法. 对于存在半像素或者四分之一像素运动估计的情况,通常是先找到整数情况下的最佳匹配,然后在其附近以更小的单位(半像素或者四分之一像素)去搜索.…

Chapter 1.Design Patterns and MapReduce MapReduce 是一种运行于成百上千台机器上的处理数据的框架,目前被google,Hadoop等多家公司或社区广泛使用.这种计算框架是非常强大,但它没有提供一个处理所谓“big data”的通用,普遍的情形,所以它能很好的解决一些问题,在处理某些问题上也存在挑战.这本书教给你在什么问题上适合使用MapReduce和怎样高效的使用它. 初次接触时,很多人没有意识到MapReduce是一种计算框架而不仅仅是一个工具.…
