opencv3 C/C++不同接口

類型	C	C++
頭文件	#include <opencv/cv.h> #include <opencv/highgui.h> …	#include <opencv2/opencv.hpp> #include <opencv2/highgui/highgui.hpp> …
主要數據類型	IplImage *img	Mat img
顯示	cvShowImage(“name”, img);	imshow(“name”, img);
等待按鍵	cvWaitKey(1);	waitKey(1);

數據轉換

IplImage -> 原始數組數據:

• IplImage* img = cvLoadImage(imagename);
• IplImage* img = cvCreateImage(cvSize(int width, int height), int depth, int channels);
• uint8_t *data = img->imageDataOrigin; //未對齊的原始圖像數據
• uint8_t *data = img->imageData; //已對齊的圖像數據

原始數組數據 -> IplImage :

• IplImage* img = cvCreateImageHeader(cvSize(width,height),depth,channels);
• cvSetData(img, (uint8_t *)data, linesize);
