详细介绍了优化算法-遗传优化算法和粒子群优化算法，给出了编程过程,(Optimization Algorithms (Genetic Optimization Algorithm and Particle Swarm Optimization Algorithm)are introduced in detail,the programm progress is gived)

特征提取提取了图像中各个标记区域的纹理特征及形状特征(Feature extraction to extract texture features and shape features of each labeled region in the image )

Representation of a Dalvik class, which is basically a set of members (fields or methods) along with a few more pieces of information.

说明：  录制一段个人的语音信号，并对录制的信号进行采样；画出采样后语音信号的时域波形和频谱图；给定滤波器的性能指标，采用双线性变换法和窗函数法设计滤波器，并画出滤波器的频率响应；然后用自己设计的滤波器对采集的信号进行滤波，画出滤波后信号的时域波形和频谱，并对滤波前后的信号进行对比，分析信号的变化；回放语音信号；最后，设计一个信号处理系统界面。(Record a personal voice signal, and recording the signal is sampled draw sampled speech signal time-domain waveform and frequency spectrum for a given filter performance, the bilinear transformation and design of filter window functions and draw the frequency response filter then filter of their own design collection of the signal filtering, to draw the filtered signal in time domain waveforms and frequency spectrum, and filtering the signal before and after comparison, analysis of signal changes playback audio signals Finally, a signal processing system interface design.)

关于高阶64APSK的优化设计程序，包括个圆半径的设置，相位角的设计，已达到最好的误码率特性(Higher order 64APSK optimal design program, including the setting of a radius of a circle, the phase angles have been designed to achieve the best error rate characteristic)

说明：  在matlab环境下实现对经典控制理论的分析和验证。(Controling experiment in matlab. )

Unitary -ESPRIT-MATLAB程序，用于近场声全息的定位，阵列信号的处理。(good，very good.)

This program compress and recostruct using wavelets. We can select level of decomposition(here maximum 4 levels are given) of images using selected wavelet. For eg:-wavelets can be haar, db1, db2,dmey............... Decomposition can be viewed in figure. (Please note that select 256X256 image for better result.) Then compression can performed, PERFL2 give compression score. Then reconstruction can be performed. Each decompsition we can choose different threshold values. For each threshold value we can calculate mse,psnr,pq(picture quality), bit ratio etc. To get pq install pqs function . (This program compress and recostruct using wavelets.
