说明：  基于人类视觉系统HVS的小波域数字图像水印 包含：嵌入、提取、分解、重构等(Based on human visual system HVS digital image watermarking in wavelet domain include: embedding, extraction, decomposition, reconstruction, etc.)

超像素实现图像分割，可以实现彩色图像分割(An EM algorithm is used for image segmentation.)

说明：  IDL读取txt，txt第一列是纬度，第二列是经度，第三列是DN值， 坐标转行列号 ，并以图像的形式输出(IDL reads TXT. The first column of TXT is latitude, the second column is longitude, and the third column is DN value. The coordinate turns the line and column number and outputs it in the form of image)

由多光谱图像的3个波段构成的RGB分量经IHS变换后，可将图像的空间特征(，)和光谱特征(H、S)分离(From multi-spectral image consisting of three-band RGB components by the IHS transform, may be characteristic of the image space (,) and spectral characteristics of (H, S) Separation)

此程序是应用于图形图像处理，基于matlab软件的二维高斯滤波算法实现。(This program is applied to graphics and image processing, based on MATLAB software two-dimensional Gauss filtering algorithm.)

六次迭代使三角形三条线分形折叠，最后组成雪花(Six iterations make triangles become snow)

SART图像重建代码 基于C++ 主要用于CT等射线处理(code of image and with a wide application of CT, x-RAY , ETC)

基于SURF特征点的图像配准代码，可实现两幅图的特征提取及匹配(SURF feature points based on image registration code)

两片镜子拼成的六边形拼接镜模型~~~~~~~(A hexagonal splicing mirror model composed of two mirrors~~~~~~~~~)

说明：  二维原始Otsu算法的MATLAB实现和其对应的文献。实现效果很好。(MATLAB realization of two-dimensional original Otsu algorithm and its corresponding literature. To achieve good results.)
