说明：  Matlab环境下的几个数字图像处理实验，包含图像灰度变换、直方图均衡化、直方图匹配、邻域平均、局域增强、中值滤波、图像的锐化等(Matlab environment, several digital image processing experiments, including the image gray level transformation, histogram equalization, histogram matching, neighborhood average, local enhancement, median filtering, image sharpening, etc.)

The Block-Matching and 3D Filtering (BM3D) algorithm is a computationally scalable algorithm based on this novel denoising strategy. It achieves state-of-the-art denoising performance in terms of both peak signal-to-noise ratio and subjective visual quality.

介绍了一种可在较短时间内检测到数字电视国标系统工作模式的方法。该方法利用帧头PN序列和PN序列扩展保护部 分的相关特性、循环特性以及0FDM信号部分的周期特性进行判决，可达到很好的检测效果，该方法同时可加入跟踪模块对系统 工作模式的突然改变作出反应。还介绍了两种可以在硬件资源和性能上进行折中的检测方法(Describes a method can be detected in a relatively short period of time to a digital television GB system working mode. The method utilizes the correlation characteristics of the the header PN sequence and the PN sequence extension protective portion, the cycle characteristics of the cycle the characteristics and 0FDM signal portion judgment can achieve good detection results, the method at the same time tracking module may be added to the system working mode sudden change the response. Also describes two hardware resources and performance compromise detection method)

对于pso有详尽的程序，包含数个测试函数并对于PSO有详细的介绍(For the pso have detailed procedures, including several test function and a detailed introduction to pso )

Robert,sobel图像轮廓提取代码，不是matlab自带函数！(Robert, sobel image contour extraction code, not matlab own function!)

提取某合成信号的三个频率成分，设计相应的滤波器，matlab源程序(Extract the three components of a mixed signal via a lowpass,bandpass and highpass filter.)

偏微分图像处理MATLAB程序 (包括水平集插值等插值方法）(MATLAB partial differential image processing programs (including the level set interpolation interpolation methods))

Mie散射计算，另包含相对尺度和复折射率的计算程序(Mie scattering calculations, and contains the relative scale and complex refractive index of the calculation program)

基于粒子群算法的高速公路速度可变控制。可以用来仿真(Based on particle swarm optimization variable speed control of the highway. Simulation can be used to)

说明：  谐波小波滤波再加上随机减量，谐波小波相当于带通滤波器，效果很好(Coupled random harmonic wavelet filter reduction, harmonic wavelet is equivalent to band-pass filter, the effect is very good)
