基于Bandlet小波的图像去噪研究，具有较好的效果。(Bandlet wavelet-based image denoising, with good results.)

数字图像处理源代码绝对好用包括一些最基本了图像处理，例如增强(digital processing)

提取糖尿病视网膜病变眼底图像上硬性渗出。将彩色图像转为灰度图，对灰度图进行形态学处理、去背景、阈值分割，最终将原图上的硬性渗出区域用绿色标记出来。(this word is to extrac the hard exudates on diabetic retinopathy fundus image. The color image to grayscale on grayscale morphological processing to the background, threshold segmentation, ultimately on the original hard exudates area marked in green.)

相控阵超声成像检测，很好的一本书，从网上买的，分享给大家(Phased array ultrasonic imaging detection, a very good book, bought from the Internet and share to everyone)

说明：  Impulse response, system response, for signal processing

一个基于MATLAB 7.2 (R2006a)实现的绘制一个单变量的直方图源码。(A histogram based on MATLAB 7.2 (R2006a) draw a single variable source. )

主要是多光谱多波段两幅图像的变化检测求得差异影像 大家可以参考参考 运行主程序(mian is used to difference of two images)

对张正友标定得程序重新详细标注了中文注释，方便初学者尽快入门，在最短的时间内了解程序流程，提高学习效率！(Zhang Zhengyou matlab calibration procedures, in order to facilitate a beginner, a code re-done every detail marked Chinese comments, so that we can understand the flow of the program as soon as possible!)

读入图像，对图像进行预处理，随后检测边缘，对得到的图像进行二值化，然后进行hough变换，获得圆边界，将此图与原图叠加，增强边缘(Read in the image, the image pre-processing, followed by edge detection, binarization on the image to get, and then the hough transform to obtain the circular boundary, this map and the original image overlay to enhance the edge)

不同信噪比下周期FRFT和FRFT两种方法对LFMCW信号的检测能力对比(FRFT different SNR period and the comparison of the two methods FRFT LFMCW signal detection capability)
