demons算法用来实现图像的配准，特别是医学图像的配准，已经达到了很高的精度(demons algorithm is used to achieve image registration, especially in medical image registration, has reached a very high accuracy)

说明：  利用双线性插值法，来对图像进行放大或者缩小的操作(Bilinear interpolation is used to enlarge or shrink the image)

基于链码提取的傅立叶描述子,以及傅立叶反变换对图象边界进行重建 (chain code extraction based on Fourier descriptors, and the Fourier transform of image reconstruction border)

利用形态学分水岭算法对图像进行分割，对细胞图像能达到较好的分割效果(Using morphological watershed algorithm for image segmentation, the cell image segmentation can achieve better results)

图像分割在医学图像，智能识别上的应用，虹膜识别(Image segmentation in medical imaging, intelligent recognition on the application of iris recognition)

图像的几何变换，基于VC++的MFC的。旋转、放大、缩小等(Image geometric transformation, based on the VC++ the MFC. Rotate, zoom in, zoom out, etc.)

在matlab平台上实现对医学图像人脑部的分割采用c语言编写(In matlab platform to realize human brain medical image segmentation using c language)

图片压缩到最小源码，例程程序结合易语言图像格式转换支持库，将快照的BMP图片转换成JPG图片，再将众多JPG图片压缩到一个压缩文件中，达到减小图片体积的效果。(Image compression to a minimum source , routine program combined image format conversion easy language support library , a snapshot of BMP images into JPG image , and then a large number of JPG images into a compressed file , to reduce the effect of image volume .)

说明：  为了达到较好的隐藏效果，本文采用游程编码的方法在二值图像中隐藏信息。秘密信息嵌入时修改二值图像的游程长度，如果秘密信息为是0，则修改该游程长度为偶数；如果秘密信息的取值与游程长度的奇偶性相匹配，则不改变游程长度。提取时根据游程长度奇偶性提取出秘密信息。在信息隐藏时，改变游程的奇偶性时通过对下一个游程的第一个像素值进行修改，因此当下一个游程长度为1时通过改变当前有成的值实现。(In order to achieve better hiding effect, we use run length encoding method to hide information in two value images. When the secret information is embedded, the length of the travel length of the two value image is modified. If the secret information is 0, the length of the travel length is even even. If the value of the secret information is matched with the parity of the length of the run, the length of the journey is not changed. The secret information is extracted according to the parity of run length. In information hiding, changing the parity of the journey is modified by the first pixel value of the next run, so the current length is 1 by changing the current value.)

基于lsb的图像信息隐写算法 利用MATLAB实现(lsb-steganography)
