PCA

通过MATLAB读取心电数据。hea,dat,art文件并显示在matlab上面(Read by MATLAB ECG data. the hea, dat, art files and displays the above in matlab)

返回从不同数组中取数据的组合 比如输入两个数组{1 2} {3 4}， 返回值为 {1 3} {1 4} {2 3} {2 4}(Back to take a combination of data from different array such as input two arrays {12} {34}, return value {13} {14} {23} {24})

this is code for finding and tracking feature points

PROJECT 02-02 Reducing the Number of Intensity Levels in an Image (a) Write a computer program capable of reducing the number of intensity levels in a image from 256 to 2, in integer powers of 2. The desired number of intensity levels needs to be a variable input to your program. (b) Download Fig. 2.21(a) from the book web site and duplicate the results shown in Fig. 2.21 of the book.
