图像分割(阈值分割和区域生长)vc++代码

实验6 图像分割

1、 阈值分割法

实验代码及结果：

#include "cv.h"

#include "highgui.h"

#include "stdio.h"

#include "stdlib.h"

#include <math.h>

int main( int argc, char** argv )

{

IplImage* pImg=0; //声明IplImage指针

int height,width,step,channels;

uchar *data;

int i,j;

//载入图像

pImg = cvLoadImage("2.jpg",0); if( !pImg )

{

printf("Image was not loaded.\n");

return -1;

}

//获取图像信息

height=pImg->height; width=pImg->width; step=pImg->widthStep; channels=pImg->nChannels; data=(uchar *)pImg->imageData; printf("Processing a %d*%d with %d channels\n",height,width,channels); int MaxP=0; float t,T,m=0,n=0; float w0,w1,u0,u1,u;

double q2=0,temp=0;

cvNamedWindow( "win1", 1);//创建窗口

cvShowImage( "win1", pImg );//显示图像

//计算最大灰度值MaxP

for(i=0;i<height;i++) for(j=0;j<width;j++)
