这是一个用在Matlab中对二维图像进行特征点提取的代码(This function returns IMAGE s SIFT keypoints)

Partition index is a measure ofvalidity similar to partition coeGcient, based on using Pj = ci=1 (uij)m as a measure ofhow well the jth data point has been classi- 2ed. The closer a pixel is to a codebook entry, the closer Pj is to one. Ifa pixel becomes an outlier to all cluster centers, the value of Pj approaches 1=cm − 1, which is the minimum value it can have.

基于LMS算法的两路信号的典型自适应噪声对消求解，程序已调试可运行，结果准确。(Adaptive Noise LMS algorithm based on a typical two-way signal cancellation solving, debugging procedure has been run, results are accurate.)

最小二乘支持向量机，LS_SVM.m为主函数，normalization.m为归一化函数，release.m为反归一化函数。(Least squares support vector machine, LS_SVM.m is the main function, normalization.m is the normalization function, release.m is the normalization function.)
