image-repair

光线跟踪，计算机图形学的实验，实现的是消隐，光线之间的遮挡等(Ray-tracing, computer graphics experiments, realize that the hidden light, such as between the block)

对图像进行细化，本实验的细化对象是一组指纹二值图。(Image refinement, the refinement of the experimental object is a set of fingerprint binary image.)

说明：  求取图像信噪比 均方差 峰值信噪比 逼真度等的matlab 程序函数(Average Absolute Difference，Signal to Noise Ratio (dB)，Peak Signal to Noise Ratio (dB)，Image Fidelity，Mean Square Error，The difference between restoredimg entroy and originalimg，entroy)

说明：  两种图像分割方法，迭代阈值分割和大津阈值分割(Two image segmentation methods, iterative threshold segmentation and Otsu threshold segmentation)

LSD直线检测 基于LSD的直线提取算法(line segment detector)

说明：  matlab图像处理用于目标分割，分割后的图像在用形态学滤波处理(matlab image processing for object segmentation, image segmentation using morphological filtering deal)

zemax非序列下gaussian光束的matlab程序（包括zemax演示源文件）(zemax sequence under non-gaussian beam matlab program (including zemax demo source files))

简单的huffman编解码例子，对于初学者会有很大的帮助。(Simple huffman codec examples, for beginners, there will be a great help.)

图像的奇异值分解，可用于图像的压缩和去噪等。(Singular value decomposition of the image, the image can be used for compression and denoising images and the like.)

说明：  地形分块下的匹配导航算法仿真程序，算法包括最优分块算法和匹配定位算法的仿真(Simulation program of matching navigation algorithm under terrain block, including the simulation of optimal block algorithm and matching positioning algorithm)
