edge-based active contour segmentation

说明：  利用共轭梯度法，追赶法，龙格库塔法来求解问题的源程序，适用于计算方法初学者(The source program of using conjugate gradient method, pursuit method and Runge Kutta method to solve the problem is suitable for beginners of computational methods.)

UWB信道的仿真程序，是一个比较经典和难得的程序！(UWB channel simulation program, is a more classic and rare procedure!)

A motion picture presents a continues phenomena as a sequence of frames. We perceive continuity by "filling in the gaps" and "smoothing out " the missing information. While faster motion requires more frames during a given time period, there is a point where more frames per second yield no further improvement. The "sampling speed" must be fast enough to allow "appropriate averaging of dead times between frames", but need not accommodate motion too fast to be seen by a human. The above description is somewhat analogous to sampling of audio signals. The sampling rate depends on how fast the signals vary (the highest frequency we hear). Nyquist showed that sampling frequency exceeding twice the audio bandwidth is sufficient to include all the signal information, preserving the finest details up to half the sampling rate

Clonal selection algorithm with matlab, and applications

基于MATLAB用于提取语音信号的特征参数如倒谱，语谱等，可以方便的检测出语音信号的基频，共振峰。(Cepstrum based on MATLAB is used to extract the characteristics of the speech signal parameters such as language spectrum, can easily detect the speech signal fundamental frequency, formant.)
