利用hough变换检测直线的matlab实现，希望对初学者有用.(Detection using hough transform matlab linear realize, I hope useful for beginners.)

文件主要是对利用压缩感知对MRI进行数据重构，重构方式是基于全变分共轭梯度法(the folder contains some Matlab codes used for applying compressed sensing(CS) in MRI. morever, these codes are based on BP-TV.)

在matlab上的Asift程序，在原有基础上有所改进，程序可以出色地实现图像的识别，匹配，效果相比SIFT，SURF等有大幅提高(In matlab Asift program improvements based on the original, the program can achieve excellent image recognition, matching, compared to the effect of SIFT, SURF, etc. have greatly improved)

这是一个K中心点聚类算法C实现的,希望对大家有用(K this is a clustering algorithm C to achieve a focal point, and I hope useful for everyone)
