图像显示：#include "highgui.h"int _tmain(int argc, _TCHAR* argv[]){ IplImage *a = cvLoadImage("lena.jpg"); cvNamedWindow("lena", 1); cvShowImage("lena", a); cvWaitKey(); cvReleaseImage(

CV_8UC1对应unsigned char CV_8SC1对应signed char CV_16UC1对应unsigned short CV_16SC1对应signed short CV_32UC1对应unsigned int或者unsigned long CV_32SC1对应signed int或者signed long CV_32FC1对应float CV_64FC1对应doub

IplImage *& CaptureFrame::getNextFrame(){ string addr = pathName + fileNames[frameCount]; const char* addrtemp = addr.data(); currentFrame = cvLoadImage(addrtemp); frameCount++; re

1.数组未初始化为0，若开辟的大小大于实际数据的大小，那么未初始化的部分会参与运算，结果就会出错 2.当CvMat类型设置为CV_32FC1时，初始化时的数组一定要是float，CvMat类型设置为CV_64FC1时，初始化时的数组一定要是double

Mat图像存储：Mat image= imread（image）；Rect rect(10, 20, 100, 50);Mat image_roi = image(rect);IplImage*图像存储：CvSize size= cvSize(40,50);//区域大小cvSetImageROI(pSrc,cvRect(60,70,size.width, size.height));//设置源

opencv1.0,IplImage类型存储图像数据，3通道void print_img(IplImage* img){ int x,y; FILE *file; file = fopen("1.txt", "w"); uchar* data = (uchar *)img->imageData; int step = img->widthStep / siz
