信号EMD分解与重构

说明：  这是用小波变换模极大值重建信号的源程序，数据是一心电信号，在matlab6。5下实现，来源于胡广书的《现代信号处理教程》附属光盘，现提供给大家供大家学习参考，滤波部分可以根据个人情况进行修改。程序包含四个部份，其中wave_peak实现信号的分解并求出模极大值(This is the wavelet transform modulus maxima reconstruction of the source signal, data signal is bent in matlab6. 5 under, and from the HU-book "modern signal processing Guide" CD subsidiary, it is available to everyone for your study reference, filtering can be part of the personal changes . Procedures include four parts, with wave_peak signal decomposition and sought modulus maxima)

　　在目前的人脸图像信息处理领域中，包含有人脸识别、人脸跟踪、姿态估计、表情识别等多个研究方向，然而，所有这些研究方向都涉及到一个人脸标识和定位的问题，即必须知道人脸在图像中的位置以及尺寸——人脸检测。因此，对于一个完整的、自动的人脸信息分析系统来说，人脸检测算法是必不可少的。本文主要是对基于matlab平台的彩色图像皮肤区域分割算法及人脸检测系统的设计做了介绍。(In the face image information processing, including face recognition, face tracking, pose estimation, expression recognition research direction, however, all of these studies are related to the direction of a person the face identify and locate the problem, that is,You must know the position of the face in the image and size- face detection. Therefore, for a complete automatic face information analysis system, the face detection algorithm is essential. This paper introduced the design of the matlab platform based on the area of ​ ​ skin of color image segmentation algorithm and face detection system.)
