GDI实例3，绘制圆形、矩形等图形

在做图像处理时用遇到图像的阈值分割，这是几种图像的阈值分割方法(In doing image processing with experience image threshold segmentation, which is one of several image thresholding segmentation method)

说明：  该算法的功能是实现时频分析中多种分析方法后续处理中的图像压缩功能，进一步提高图像的时频分辨率(The function of the algorithm is to realize the image compression function in the subsequent processing of various analysis methods in time-frequency analysis, and further improve the time-frequency resolution of the image)

opencv读取一个视频并设置其播放帧率播放速度(use opencv to read a video and change the rate)

使用canny边缘检测算法，提取图像轮廓(Canny edge detection algorithm is used to extract image contour.)

Brown noise generated in Matlab

说明：  噪声估计法，先定位噪声点，再实行去噪处理(Noise estimation method, first locate the noise points, then implement denoising.)

对于原始图像 < f5.tif > ，实现下列结果。 a.用平均滤波器平滑原始图像得到的模糊图像 b.用拉普拉斯算子增强上述a得到的模糊图像 c.用拉普拉斯算子增强原始图像 (For the original image <f5.tif>, to achieve the following results. a. smoothing filter with an average original image was blurred b. using Laplacian enhancement get a blurred image above c. using Laplacian enhancement of the original image)

颜色特征提取，为matlab 源文件，是底层图像处理的基本特征之一，是本人在做硕士论文时收集修改的代码(Color Feature Extraction for the matlab source file, the underlying image processing are one of the essential features)

自己修改的基于closed-form的程序，对外国程序在时间上有两倍的改善，能对在复杂背景下的图片，通过画一些简单的前景线，背景线，抠图出前景(it is about matting foreground when the interested ared is located under complixed background,and then choosing some other beautiful background,you can create new image,which brings you some special feelings.thanks.)
