finger recognition in matlab

说明：  基于内点法的解l2_l1和l2_TV优化问题的matlab代码(Interior point method based on the solution l2_l1 and optimization problems l2_TV code matlab)

The COFDM simulation

利用matlab开发的HSV空间分割的，手势识别程序，效果较好，背景复杂的情况下识别率也很高！！！(Recognition rate is also high in the case of using matlab development of gesture recognition program, the better the background is complex! ! !)

Matlab多人脸检测程序，能框出人脸，附有检测图片(Matlab multiple face detection program that can frame the face, with a detection picture)

按照给定指标采用模拟低通滤波器（巴特沃思低通）去逼近理想模拟低通滤波器 ，然后通过双线性变换法对模拟滤波器进行数字化，得到数字滤波器 。(Indicators in accordance with a given analog low-pass filter (Butterworth low-pass) to approximate the ideal analog low-pass filter, and then through the bilinear transformation method of digitizing analog filters, the digital filter.)

带中文注释的主成份分析 PCA源代码在matlab的实现 (Annotated with the Chinese to achieve pca algorithm matlab)

本代码是全通系统和最小相位系统的零极点和幅频和相频的响应(The code is all-pass system and the minimum phase zero poles and frequency and phase frequency response)

基于双线性插值方法的图像缩小、放大程序，原创(Bilinear interpolation method based on image reduction, enlargement program, originality)

完成基于EMD及灰关联的航迹关联，该算法相比仅使用灰关联的算法正确率要高。(EMD completion of association and Grey' s track-based algorithm compared to Grey' s algorithm uses only the correct rate is higher.)
