运行程序，得到不同伽马因子给图像的整体明暗程度带来的变化(Run the program to get the change of the overall brightness of the image with different gamma factors)

该程序实现了harris角点的提取以及其在两幅影像上的配准结果，希望对大家有用(The program implements the harris corner extraction as well as their two images on the registration results, we hope to be useful)

利用误差扩散算法中的Floyd-Steinberg抖动算法来对图像进行二值化处理，从而方便图像调频加网输出(The use of error diffusion algorithm of Floyd-Steinberg dithering algorithm to image binarization treatment, thus facilitating image output FM Screening)

使用kmeans算法对图像进行分割，先对图像进行了rgb到lab的转换(Use kmeans algorithm for image segmentation, the first image of rgb to lab conversion)

对脑部ct图像的头骨形状进行区域生长算法的运算(Ct images of the brain the skull shape of region growing algorithm for computing)

说明：  该文件可以读取MRI raw data，磁共振指的是自旋磁共振（spin magnetic resonance）现象。其意义上较广，包含核磁共振(nuclear magnetic resonance, NMR)、电子顺磁共振（electron paramagnetic resonance, EPR）或称电子自旋共振（electron spin resonance, ESR）(The file can read MRI raw data, Magnetic resonance refers to the phenomenon of spin magnetic resonance. It is broader in meaning and includes nuclear magnetic resonance (NMR), electron paramagnetic resonance (EPR) or electron spin resonance (ESR))

提取图像的局部二值特征；广泛用于纹理特征提取 具有旋转不变性(Extract local two value features of images; widely used in texture feature extraction. Rotation invariance)

说明：  matlab编写高斯光束高斯光束模拟的焦点附近光场分布(Matlab programming of Gaussian beam the distribution of light field near the focus of Gaussian beam simulation)

双目立体匹配中获取图像对的视差图，可用于后续的三维重建工作。(Binocular stereo matching to get the image on the disparity map can be used for subsequent 3D reconstruction.)

说明：  自己编写的基于直方图均衡化以及边缘增强的程序！(I have written based on histogram equalization and edge enhancement procedure!)
