Matlab implementation of image segmentation/edge preserving filtering algorithm

一个人体运识别跟踪的示例程序，里面附带了一个运动视频，运行run.m文件。程序里包含了轮廓提取，跟踪算法，很好的tracking学习程序(An example program for personal movement recognition and tracking is attached to a sports video, running run.m files. The program includes contour extraction, tracking algorithm, good tracking learning program.)

重要是实现通过瑞利信道的QPSK的仿真，同时给出了其误码率的仿真(Important thing is to achieve through the Rayleigh channel QPSK simulation, while its error rate is given simulation)

说明：  对原始图像添加高斯噪声，并用邻域平均和中值滤波法进行滤波，并可以进行对比。(Gaussian noise added to the original image, and use neighborhood average and median filtering method for filtering, and can be compared.)

说明：  Today’s wireless networks are characterized by a fi xed spectrum assignment policy. However, a large portion of the assigned spectrum is used sporadically and geographical variations in the utilization of assigned spectrum ranges from 15 to 85 with a high variance in time. The limited available spectrum and the ineffi ciency in the spectrum usage neces- sitate a new communication paradigm to exploit the existing wireless spectrum opportunistically

matlab RS 分形程序，用于稳定性检验，也可以进行周期长度估计，当统计量图形形状发生变化，就发生突变，短期记忆消失(Fractal matlab RS procedures for stability testing, but also can estimate the cycle length, when the statistic graphics shape changes, on the mutation, the disappearance of short-term memory)

调频广播中，为了提高音频高频率端的信噪比，在发射端进行的预加重处理。(FM radio, in order to improve the high frequency end of the audio signal to noise ratio, performed at the transmitter pre-emphasis.)

bit error rate versus capacity

用布莱克曼窗设计数字带通滤波器,讲解了窗函数的基本原理，设计的过程等(The Blackman window design digital band-pass filter, to explain the basic principles of the window function, design process)
