k-svd_second

matlab做的标定程序，包括角点检测与张正友标定算法做的，有界面 (matlab to do the calibration interface, including the corner detection algorithm and Zhang Zheng-you do calibration)

在边缘检测之后得到的边缘不一定是完整的，利用这个函数可以将个线段生长一些，然后连接起来，成完整的形状(At the edge of the edge detection after get is not necessarily complete, use this function can be a line segment to grow some, and then connect, into the shape of a complete)

求质心到图像轮廓边缘的距离，并将其用figure表示出来(The distance from the center of mass to the edge of the image contour)

CV模型水平集代码，包括图片、代码和运行结果(The level set evolution function of the CV model)

很有用的gdal库，并且已经编译好。请多多指教!(It is a very good resource！Please download！！)

基于Harris角点检测的图像拼接matlab实现， 主要内容包括Harris角点检测，NCC,RANSAC以及2幅图像的拼接(A image mosaicing algorithem which based on Harris corner feature detection achieved in matlab. The main contents include the Harris corner detector, the NCC, the RANSAC and two image mosaicing)

说明：  用于浏览和检索的图像纹理特征提取，使用gabar滤波器提取纹理特征。(For browsing and retrieval of image texture feature extraction, texture features extracted using gabar filter.)

数字图像插值增减算法。数字图像插值增减算法。数字图像插值增减算法 (reduce)

说明：  压缩文件中的代码可以读取图片并计算绿色植被的归一化植被指数，直接在IDL中打开即可使用(The code in the compressed file can read pictures and calculate the normalized vegetation index of green vegetation,and you can open it directly in IDL and use it.)

说明：  基于DCT域的图像数字水印技术，水印嵌入过程，提取过程，以及嵌入水印的抗干扰性等。(Based on the DCT domain image digital watermark technology, watermark embedding process, extraction process, as well as embedded watermark anti-interference and so on.)
