天津大学的ACM队的计算几何的资料合集,有兴趣的人看看吧,有点帮助的就好,c++写的...

SIFT算法由D.G.Lowe 1999年提出，2004年完善总结。后来Y.Ke将其描述子部分用PCA代替直方图的方式，对其进行改进。 2 SIFT 主要思想 SIFT算法是一种提取局部特征的算法，在尺度空间寻找极值点，提取位置，尺度，旋转不变量。 -a method for extracting distinctive invariant features from images that can be used to perform reliable matching between different views of an object or scene. The features are invariant to image scale and rotation, and are shown to provide robust matching across a a substantial range of affine distortion, change in 3D viewpoint, addition of noise, and change in illumination. The features are highly distinctive, in the sense that a single feature can be correctly matched with high probability against a large database of features from many images.

This packet contains the MATLAB files that fit a hidden Markov tree model to the contourlet coefficients of images. The files require the contourlet Toolbox, which can be downloaded from http://www.programsalon.com/downloads121/sourcecode/graph/detail516305.html.
