梯度锐化：通过处理使图像的棱角更加分明，边缘对比明显-Gradient sharpening: by processing the image edges and corners to make more clear, obviously the edge contrast

本程序基于Matlab,初步实现图像增强的基本操作,实现 图像明暗度调整， 图像旋转，更改颜色显示方式，直接灰度调整，图像求反，动态范围压缩，显示原始图像直方图，直方图均衡化，滤波增强等功能-This procedure based on Matlab, the initial realization of the basic operation of image enhancement, image brightness adjustment, image rotation, change the color display, direct gray-scale adjustment, for anti-image, dynamic range compression, display the original image histogram, histogram equalization , enhanced features such as filtering

VC编写的基于PCA和LBP的人脸识别程序-VC prepared by the PCA and the LBP-based face recognition program

The transformation parameters are specified by the user by editing the values of the rotation, scale (x and y), and shear (x and y). The translation is not icluded because it can be easily (normalized or) removed from the image by subtracting the shape cetroid. The affine matrix and the affinr transformation are computed using Matlab Image Processing Toolbox functions: maketform and imtransform. So this program is only demonstrates and facilitates the computation and the applying of these functions to a 2-D image. -The transformation parameters are specified by the user by editing the values of the rotation, scale (x and y), and shear (x and y).

沃尔什（Walsh）变换是一种可分离变换，广泛应用于图像处理。本代码实现了图像Walsh变换，非常经典，带图片可测试.-Walsh (Walsh) is a separable transform transform, which are widely used in image processing. Implementation of the code of the image Walsh transform, very classic, with pictures can be tested.

这个是彩色图像分割方法。与RegionExtract采用的方法不同。 首先rgb转换成hsv，对h分量进行直方图分割，得到直方图的峰值和峰谷。利用得到的峰值和峰谷进行区域分割，这样会得到很多的小区域，对这些小区域进行区域合并，区域合并的终止条件是：区域一致性距离在某个固定的阀值之间，比如20或者在某个自适应阀值（该阀值自动计算）。注意：区域合并在luv空间进行。-This is a method for color image segmentation. With the different methods used RegionExtract. First rgb convert hsv, components of the h histogram segmentation, the histogram peak and peak and valley. Utilization of the peak and peak-valley regional partition, it would receive many of the small area of these small regional regional merger, regional merger termination conditions are: the regional consistency of the distance between a fixed threshold, such as 20 or in a self-adaptive threshold (the threshold automatically calculated). Note: regional merger in luv space.
