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：
