用MATLAB来实现简单图像特征点提取和匹配(Using MATLAB to implement a simple image feature extraction and matching)

提取图像相位一致性特征，进行图像配准，内附实验图片(Image feature extraction phase coherence)

nist部分算法研究，序列检测，频率检测，累加和检验检测(nist part of the algorithm research, sequence detection, frequency detection, cumulative and inspection)

基于otsu的自适应阀值canny边缘检测(adaptive canny edge detection based on otsu)

Random ppm modulated analog signal under Complete class-based image processing, contains all of the source code, auto image, Correlation analysis process matlab method.

说明：  find_center:寻找图像的形心，即图像几何中心点的检测。 otsu:otsu分割 sobelNedge：sobel边缘检测 catch_point:全局阈值分割函数(Find center: find the centroid of the image, that is, the detection of the geometric center of the image. Otsu: Otsu segmentation Sobel edge: Sobel edge detection Catch point: global threshold segmentation function)

图像处理技术边缘检测源码Source image processing edge detection(Image processing edge detection source Source image processing edge detection)

otsu算法应用于图像分割--图像分割-直方图(Otsu algorithm is applied to image segmentation image segmentation- Histogram)

抽取子图像: 通过一个随机混沌标签序列从原图像中抽取 对子图像加密:小波变换 ,在高频部分加密 重构原图，把加密好的子图像重新放回到原图像中 (from sub-images : a random chaotic sequence label from the original image from a tradition image encryption : wavelet transform, the high-frequency part of remodeling the maximum encryption, encrypted good son to re-up images back to the original image)

基于半色调图像的数据隐藏即加数字水印，针对半色调图像，所以使用的是DHSPT算法，算法较容易理解，简单，嵌入效果相对较好(Hidden based on the halftone image data plus digital watermark for halftone images, use DHSPT algorithm, the algorithm is easy to understand, simple, embedded effect is relatively good)
