在学习了数字信号处理、信号与系统、建模与仿真及其医学应用等课程的基础上， 学习一类典型的生物医学信号--脑电的测取、FFT 频谱分析、以及应用数字滤波方法提 取脑电的频带（8－13Hz）信号及其特性分析。(Epilepsy section of the brain wave extraction and analysis of characteristics of the course design report )

将一幅图像以jpeg的形式进行压缩，对初学者很有用(Jpeg form of an image compression, very useful for beginners)

ROA和CANNY结合的算子,图像效果还行吧(it combine the CANNY and the ROA，the result shows it was perfect)

品质因子可调的离散小波变换工具箱，可通过参数灵活控制小波函数的频域窗宽(Discrete wavelet transform toolbox with quality factor adjustable, flexible control parameters through the wavelet function in the frequency domain window width)

C#+EmguCV机器视觉开发平台，功能：基本的图像处理工具、随意配置执行流程、二维码识别、文字识别等等。(C+EmguCV machine vision development platform, functions: basic image processing tools, arbitrary configuration of the execution process, two-dimensional code recognition, character recognition and so on.)

说明：  基于matlab的简单手势识别代码，初学者可自行下载。(Simple gesture recognition code, beginners can download.)

SSIM是衡量图像质量的另一个标准，比PSNR略好。此为计算图像SSIM的代码(SSIM is another measure of image quality, slightly better than PSNR. The code is to calculate SSIM.)

基于马尔科夫随机场算法(MRF)的图像分割(Image segmentation of Markov random field algorithm)

相位恢复算法,利用恢复图像在时域必须是正实值以及正逆傅里叶变换进行恢复(phase retrieve)
