codes

说明：  用于相位解缠，提供好的解缠方法和解缠效果，能够更好的得到真实值(For phase unwrapping, unwrapping methods provide good wrapped around the effect of reconciliation that can better be the true value)

说明：  一种很好的基于改进的椭圆检测算法值得一看要(A good improvement on the ellipse detection algorithm to see)

说明：  使用opencv语言绘制所有轮廓后根据轮廓长度丢弃小轮廓(Opencv draw all contours of the language used under the contour length of the drop after the small contour)

HOG（方向梯度直方图）图像特征提取，以lena图像作为示例(HOG (Histogram of Oriented Gradients) image feature extraction, image as an example to lena)

利用霍夫变换检测直线，园，椭圆，曲线，简单有效，用用方便(Using Hough transform to detect straight lines, park, oval, curve, simple, effective, easy to use with)

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))

该程序主要是对一幅图像进行动漫风格化 总体上，把照片变成动漫化风格分以下几步： （1）膨胀图片让其亮暗分明 （2）区域平滑 （3）增强锐化，以突出显示边缘线条。(The program is mainly a cartoon style animation style On the whole, take the photo into the animation style and divide the following steps. (1) the expansive picture makes it bright and dark (2) regional smoothness (3) sharpening to highlight the edge lines.)

各向异性扩散相干斑降噪，可以在增强边缘的同时滤出噪声，效果很好！(Anisotropic diffusion, coherent noise can enhance the edge of the filter out the noise at the same time, the effect is very good!)

SAI图像插值算法 可插值uint8 uint16 图像(SAI image interpolation algorithm can interpolate uint8 uint16 image)

此程序用于画混沌系统的相图及其分叉图，使用时只需要写出相应的混沌微分方程，便可画出相应的图(This procedure for drawing the phase diagram of chaotic systems and its Poincare section, when used only need to write the corresponding chaotic differential equations, will be able to draw the corresponding graph.)
