天在维普下载了一篇SPIHT算法改进的论文，（耿兴云，《基于改进SPIHT的静态图像编码》，电脑知识与技术：学术交流-2007年5期），我根据该文提出的改进算法，用Matlab来实现，却发现改进算法的程序运行速度比原算法还要慢，希望有兴趣的朋友进来看看，评论一下原因。(Days in the VIP downloaded a SPIHT algorithm to improve the paper, (Gengxing Yun, " based on improved SPIHT still image coding," Computer Knowledge and Technology: 5-year academic exchange-2 007), in accordance with this paper the improved algorithm Matlab to achieve, but found that the improved algorithm runs faster than the original algorithm is also slow, hope to have interested friends come to see, comment on why.)

this code is about vissel blood extraction by matlab

this matlab model describes harmonics generation for study very useful

为了避免直接对rgb图像处理时出现颜色失真，常把彩色图像由rgb空间转为hsv空间，完成相应处理后，再逆变换至rgb空间。(In order to avoid image processing directly on the rgb color distortion occurs, often the color image from the rgb space into hsv space to complete the appropriate treatment, and then inverse transform to the rgb space.)

基于无差拍的有源电力滤波器（APF）的仿真设计，包括（谐波检测， 电流跟踪环节） Z域(spwm调制)(Deadbeat based Active Power Filter (APF) simulation design, including (harmonic detection, current tracking links) Z domain (spwm modulation))

Brain waves extraction, Brain waves energy and brain laterality using Fast Fourier Transform

动目标检测（MTD）领域的仿真，画出了加汉明窗之后的频率响应曲线，经调试，可以运行(Moving target detection (MTD) in the field of simulation, draw the frequency response curve after Hamming window, debugging, you can run)
