在matlab中GUI环境下通过摄像头读入视频并处理 手记（未完）

目标：在matlab中GUI环境下通过摄像头读入视频并实时处理（实时可能比较困难）

1、建立GUI界面，通过摄像头读取视频，并灰度化处理。  完整的m文件如下。（matlab2010a）

function varargout = faceDetection(varargin)
% FACEDETECTION M-file for faceDetection.fig
%      FACEDETECTION, by itself, creates a new FACEDETECTION or raises the existing
%      singleton*.
%
%      H = FACEDETECTION returns the handle to a new FACEDETECTION or the handle to
%      the existing singleton*.
%
%      FACEDETECTION('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in FACEDETECTION.M with the given input arguments.
%
%      FACEDETECTION('Property','Value',...) creates a new FACEDETECTION or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before faceDetection_OpeningFcn gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to fa
