基于OPENCV的灰度化，平滑处理

1、加载图像
#include "highgui.h"
#include "cv.h"
#include "cxcore.h"
#include <cvaux.h>
int main( int argc, char** argv[] )
{
  IplImage* img = cvLoadImage("D:\\2.jpg",-1);
  cvNamedWindow("Example1", 0);
  cvShowImage("Example1", img );

  cvWaitKey(-33);
  cvReleaseImage( &img );
  cvDestroyAllWindows( );
  return 0;
}

2、灰度化

#include "highgui.h"
#include "cv.h"
#include "cxcore.h"
#include <cvaux.h>
int main( int argc, char** argv[] )
{
  IplImage* img = cvLoadImage("D:\\11.jpg",-1);
  cvNamedWindow("Example1", 0);
  cvShowImage("Example1", img );
  IplImage * img1 =cvCreateImage(cvGetSize(img),IPL_DEPTH_8U,1);
  cvCvtColor(img,img1,CV_BGR2GRAY);
