Image-Matching

生成静态散斑图，通过快速傅里叶变换，得到激光散斑图。(Generate static speckle pattern)

图像特征隐写分析，用于分析图像是否含有秘密信息(Image feature steganalysis for the analysis of the image if it contains confidential information)

本文提出了一个关于图像抠图的方法，它的抠图效果不错，而且作者的主页上提供了MATLAB的源码，可以看一下。(This paper presents a method on the image matting, matting it well, and the author' s home page provides a MATLAB source code, you can see it.)

虹膜识别的内外边缘图像分割，包括瞳孔的分离，还有外边界的分离(Iris recognition both inside and outside the edge of image segmentation, including the separation of the pupil, as well as outside the borders separating)

最邻近插值的matlab实现代码，可以对图像进行插值，插值的方法为最邻近插值法(The nearest neighbor interpolation matlab code, image interpolation, interpolation methods nearest neighbor interpolation)

主成分分析程序,应用于图像特征提取，数据降维等方面 (the code of PCA)

说明：  Principal Warps: Thin-Plate Splines and the Decomposition of Deformations

使用统一资源定位符类URL实现文件下载，同时ImageIO也可以实现(class URL download file)

说明：  用于去除背景，得到原图与背景相减的图像并二值化(boundaries defects and improve the quality of remote sensing images and improve the visual effects))

matlab检测圆心程序，基于HOUGH，附测试图像。(Detect matlab center procedures, based on HOUGH, attached to the test image.)
