第二代小波变换，基于提升格式的整数小波实现数字图像的无损压缩编码(Second-generation wavelet transform, lifting scheme based on integer wavelet realize the lossless compression of digital image coding)

demo中基本上整理了目前常用的所有边缘检测算子，并添加了自定义的frei-chen、kirsch、direcedge、PrewittCompass、RobinsonCompass边缘检测算子function函数。此外，还有Ruzon罗盘算子的matlab实现程序，能对灰度图像的边缘加以检测。(demo, basically compiled all the commonly used edge detection operator, and add a custom frei-chen, kirsch, direcedge, PrewittCompass, RobinsonCompass edge detection operator function function. In addition, there Ruzon compass operator procedures matlab realize, can be gray-scale image edge detection.)

利用gabor滤波器来进行人脸图像的处理，内部并包含多张测试图像(Gabor filter to use a face image processing, internal testing and contains multiple images)

Jsteg算法实现基于JPEG图像的信息隐藏(Jsteg algorithm information hiding based on JPEG image)

利用双线性插值，获取亚像素位置的灰度值。适用于得到sift、surf得到的特征点坐标处的灰度值获取(The gray value of sub-pixel position is obtained by bilinear interpolation)

在C语言下成功实现读取并显示bmp格式的图像。(Successfully read and display BMP format images in C language.)

水平集方法的实例演示,对于初学水平集的朋友有很多帮助。(Examples demonstrate the level set method, the level set for the beginner friends have a lot of help.)

基于引导滤波的图像信息分层算法，可实现高低频信息分离，分段处理功能(The image information hierarchical algorithm based on guided filtering can realize the separation of high and low frequency information and the segmentation processing function.)

拐点的检测，对一个图像的拐点进行检测，使用的是freeman链码的方法，检测图像中拐点的方向，确定该方向是不是拐点。(Inflection point detection, an image of the inflection point for testing, use freeman chain code method, testing the image in the direction of the inflection point, we determine the direction is inflection point. )

图像处理基本算法其中之一的图像细化(Image processing one of the basic algorithm for image thinning)
