说明：  在图像匹配中，有很多种算法。在这众多的算法中，SIFT 算法具有良好的尺度、光 照和空间旋转的不变性，所以被广泛的应用于图像匹配当中。本文对SIFT 算法的四个主要 步骤进行了简单的介绍，并将该算法应用到多色二值压缩的压缩算法当中，提高了压缩效率 并且缩小了压缩后的存储空间。(In image matching, there are many kinds of algorithms. In many algorithms, SIFT algorithm has good scale, light and space rotation invariance, it has been widely used in image matching them. In this paper, the four main steps in SIFT algorithm was brief, and the algorithm is applied to the multi-color two values of compression compression algorithms which improve the compression efficiency and reduces the compressed storage space.)
