一、简介

如何在视频流中检测到人脸以及人脸追踪。对象检测和跟踪在许多计算机视觉应用中都很重要,包括活动识别,汽车安全和监视。所以这篇主要总结MATLAB的人脸检测和跟踪。
首先看一下流程。检测人脸——>面部特征提取——>脸部追踪。

二、部分源代码

unction varargout = facedetecion(varargin)
% FACEDETECION MATLAB code for facedetecion.fig
%      FACEDETECION, by itself, creates a new FACEDETECION or raises the existing
%      singleton*.
%
%      H = FACEDETECION returns the handle to a new FACEDETECION or the handle to
%      the existing singleton*.
%
%      FACEDETECION('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in FACEDETECION.M with the given input arguments.
%
%      FACEDETECION('Property','Value',...) creates a new FACEDETECION or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before facedetecion_OpeningFcn gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to facedetecion_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
%
% See also: GUIDE, GUIDATA, GUIHANDLES
