说明：  lower的原版关于sift算法的资料，很难找的哦。本文非常详细的介绍了sift算法，并与常用的边缘检测算法作了比较，是学习sift算法的好资料。(lower of the original information on the sift algorithm, it is difficult to find, oh. This very detailed introduction to the sift algorithm, and with commonly used edge detection algorithms are compared, is the learning algorithms sift the good information.)

this is genaral techniques involves in noise cancellation and this matlab version
