PCA（主成分分析）MATLAB代码

图像变换 将图象分块(8*8)，作DCT变换，并作IDCT：DCT是一种可分离图象变换，用来图象压缩编码，IDCT用来解压缩(Image transform to image sub-block (8* 8), for the DCT transform, and IDCT: DCT is a separable transform image to image compression coding, IDCT used to extract)

这个小程序能够实现字体的滚动效果，非常有用，肯定能够帮助一些人。(This small program can be achieved fonts rolling effect, very useful and can certainly help some people.)

Display 3D Images Matlab三维图像显示(DICOM MR CT PET等) 2009年02月17日 MATLAB 7 (R14) 这是一个三维图像显示的Matlab实例程序。支持DICOM MR CT PET等图像格式。并且可以对每一帧进行图像处理，如直方图均衡、绘制，反色等。 (Display 3D Images Matlab three-dimensional image display (DICOM MR CT PET and so on) February 17, 2009 MATLAB 7 (R14) This is an example of three-dimensional image display of the Matlab programs. Support for DICOM MR CT PET and other image formats. And can carry out image processing for each frame such as histogram equalization, draw, color reverse.)
