OpenCV学习笔记-形态学
OpenCV提供了通用的形态学函数cvMorphologyEx,该函数能够实现开运算，闭运算，形态梯度，礼帽操作，黑帽操作，例题如下：
#include "StdAfx.h"
#include "cv.h"
#include "highgui.h"
#include "highgui.h"
int main(int argc, char ** argv)
{
cvNamedWindow("sourceImage");
cvNamedWindow("open");
cvNamedWindow("close");
cvNamedWindow("gradient");
cvNamedWindow("topHat");
cvNamedWindow("blackHat");
IplImage * src = cvLoadImage("test.bmp");
cvShowImage("sourceImage",src);
IplImage * temp = cvCreateImage(cvGetSize(src), 8,3);
IplImage * img=cvCreateImage(cvGetSize(src), 8, 3);
cvCopyImage(src,temp);
cvCopyImage(src, img);
//开运算
cvMorphologyEx(
src,
img,
temp,
NULL, //default 3*3
CV_MOP_OPEN,
4);
cvShowImage("open", img);
//闭运算
cvMorphologyEx(
src,
img,
temp,
NULL, //default 3*3
CV_MOP_CLOSE,
4);
cvShowImage("close", img);
//形态梯度
cvMorphologyEx(
src,
img,
temp,
NULL, //default 3*3
CV_MOP_GRADIENT,
3);
cvShowImage("gradient", img);
//cvWaitKey(0);
//"礼帽"
cvMorphologyEx(
src,
img,
temp,
NULL, //default 3*3
CV_MOP_TOPHAT,
3);
cvShowImage("topHat", img);
//cvWaitKey(0);
//“黑帽”
cvMorphologyEx(
src,
img,
temp,
NULL, //default 3*3
CV_MOP_BLACKHAT,
3);
cvShowImage("blackHat", img);
cvWaitKey(0);
cvReleaseImage(&temp);
cvReleaseImage(&src);
cvReleaseImage(&img);
cvDestroyAllWindows();
return 0;
}
运行结果为：
