OpenCVMat顏色通道分離,各通道合圖顯示

1、OpenCVMat圖像顏色通道分離(split)合成(merge),各通道合圖顯示.回OgOjhappyfisli.JPG#include#include#include#includeusingnamespacecv;usingnamespacestd;intmain(intargc,char*argv)FreeConsole();/HidetheCMDwindowif(argc!=2)std:cout請(qǐng)輸入需要加載的文件!std:endl;return-1;/讀取圖像Matimage;char*imageName=argv1;image=imread(imageName,CV_LOAD_I
