利用matlab提取红绿灯的二值图像！！！！！！(Extract the two value image of the traffic light.)

说明：  图像处理小工具箱，包括中值滤波，高斯滤波，均值滤波，canny边缘提取等小程序(Image processing toolbox, including median filter, gaussian filter, mean filter, canny edge extraction and other small procedures)

这是我本科的毕业设计做的关于医学图像的基于形状的图像检索。预处理用小波去噪 ，特征选用不变矩。(This is my undergraduate graduation design done on the medical images based on the shape of the image retrieval. Pretreatment with wavelet denoising, feature selection invariant moment.)

图像处理中的一些常用代码，包括：腐蚀操作 开启和闭合操作 形态学边界提取 形态学骨架提取 直接提取四个顶点坐标(Some of the commonly used image processing code, including: Opening and closing operation of corrosion morphology boundary extraction morphological skeleton extraction to extract four vertex coordinates)

实现了单色图像的JPEG2000编码图像和解码图像！计算其压缩比和误差，观察源图像和重构图像之间的差别！(JPEG2000 images to achieve a monochrome image coding and decoding image! Calculate the compression ratio and error, observation of the source image and the difference between the reconstructed image!)

matlab编写的harris程序,对初学者还是很有帮助的(harris program written in matlab, or helpful for beginners)

立体视觉代码。主要过程包括：harris角点检测，zncc最优策略匹配，扩散得到更多特征对应，计算disparity和对应颜色值。另外提供了两幅图片以及对应的特征匹配的结果和disparity图像。(Three-dimensional visual codes. The main process includes: harris corner detection, zncc optimal strategy for matching, the proliferation of more features of the corresponding calculation of disparity and the corresponding color value. Also provides a picture and two corresponding feature matching results and disparity images.)

ICP模型配准有二维三维两种方式，简单好用(ICP RIGID EASY 2 DIMENSION 3 DIMENSION)

读取envi的img格式的高光谱文件，是matlab对其进行处理高光谱图像，是env和matlab相同(Read envi img format hyperspectral file, is matlab to deal with hyperspectral images, is the same as env and matlab)

KSVD工具包,可以用于去噪增强等多种领域,具体方法是先训练方向,然后沿方向进行(KSVD toolkit can be used to enhance various areas of de-noising, the specific method is the first training direction, and then along the direction)
