图像清晰度评价，包含标准差，空间频阈，熵，bener(Image sharpness evaluation, including standard deviation, spatial frequency threshold, entropy, bener)

说明：  也是水平集方法的一个matlab源代码 比较经典的写的很详细 还可以做3d处理的(level is a collection of source code comparison Matlab classic written in great detail can be done to deal with the 3d)

基于窄带法编写的水平集函数，要先手动选择初始轮廓。(narrowband_CV model)

基于图像的条形码识别程序（识别EAN13码），只要条形码的背景部分是纯色，程序就能有相当强的鲁棒性。(Image-based bar code recognition program (recognize EAN13 code), as long as the background of the bar code is solid, the program can be quite strongly robust.)

说明：  EM算法是最为经典的统计图像分割方法，代码基于matlab，使用EM算法实现图像分割,源代码加实例图像，非常好用(By using EM algrithm to realize the segementation of image)

说明：  基于卡尔曼滤波的camshift算法，实现目标跟踪(CAMSHIFT algorithm based on Kalman filter for target tracking)

光学计算中跟衍射相关的很多公式，有详细说明，很好用(err)

该函数用来实现快速离散余弦变换。该函数利用2N点的快速付立叶变换来实现离散余弦变换(This function is used to implement fast discrete cosine transform. 2N points of the function using the fast Fourier transform to achieve the discrete cosine transform)

显示图像灰度，可以鼠标点击显示的起始位置及设置显示区域的大小(show the gray of picture ,can click the position and set the scales)

说明：  区域生长法的图像分割方法，效果分厂不错，值得借鉴！(Region growing image segmentation method, the effect of a good factory, worth learning!)
