pftest

实现图像中细胞的提取，并计算出细胞与核仁面积之比的可视化程序(Extraction of cells in the image, and calculate the cells with nucleolar area ratio of the visualization program)

边缘检测算法的比较，有susan算子，log算子，prewitt算子(Comparison of edge detection algorithm, there is susan operator, log operator, prewitt operator)

目前最重要的图像变化检测评价标准：roc曲线，以及roc曲线下面积。(ROC curve of image change detection)

利用IDL读取二进制文件、*.HDF、*.nc文件的属性(read*.hdf、*.nc file on IDL)

free-vision library,计算机视觉C++库，含有SAMPLE,非常经典！(free-vision library, computer vision C library, containing SAMPLE. very classic!)

BP神经网络，可以处理图像进行分类等各种处理的源码(BP neural network image processing source code)

本实验要求编写一个计算压缩-解压缩图像的均方根误差、均方信噪比的程序。该程序是一个通用程序。编写程序产生图示的结果。使用上面的保真度准则程序计算可视信息的损失特性。(Prepared in this experiment, a calculation of compression- decompression of the root-mean-square error of image, mean square signal to noise ratio of the procedure. The procedure is a common procedure. Picture shows the preparation of the results of procedures. The use of the above criteria for the fidelity of calculated loss characteristics of visual information.)

基于小波阈值的去噪方法，可以通过改变不同的参数达到不同的效果。(Wavelet threshold de-noising method can achieve different effects by changing the different parameters.)

hough变换检测直线代码在matlab下的运行(hough transformation)

图像椒盐噪声去除研究程序，在matlab条件下编译的，主要应用中值滤波法对噪声的去除．(Impulse Noise Removal procedures, the conditions under Matlab Compiler. Application of the main method of filtering noise removal.)
