计算DWT小波变换的JND值（恰可察觉性失真），用于图像水印的实现。以及DCT的水印实现(Calculate the DWT wavelet transform value of JND (Just Noticeable Distortion) for the image watermark. As well as the watermark of the DCT)

程序实现人脸特征的检测和定位，可以识别并标注眉毛，眼睛，鼻子，嘴巴以及耳朵。能用于单人和多人脸图的检测识别，效果不错。(This is a human facial feature detection and location program. It can be applied to detect both single and multiple face images. )

基于MATLAB 的带阻滤波器设计,是我自己做的，的确还不错，带宽是200HZ(JI YU MATLAB DE DAI ZU LV BO QI SHE JI)

设计一个低通数字滤波器，满足如下设计指标： 通带截止频率：0.2pi，通带波动：1dB 阻带截止频率：0.3pi，阻带衰减：15dB 要求：分别采用巴特沃斯、切比雪夫Ⅰ型、切比雪夫Ⅱ型和椭圆滤波器原型进行设 计，比较各种设计的阶数、实际阻带衰减，分析实验结果 (Design a low pass digital filters that meet the following design specifications: passband cutoff frequency: 0.2pi, pass-band fluctuations: 1dB stopband cutoff frequency: 0.3pi, stop-band attenuation: 15dB requirements: respectively Butterworth, Chebyshev Ⅰ, Ⅱ and Chebyshev prototype elliptic filter design, comparing the order of the design, the actual stop-band attenuation, analysis of experimental results)
