So if you have: IplImage *img;
load your image in img, delete this line: cv::Mat image = cv::imread(file_path , 0); and replace with: cv::Mat image(img); And remember: - you will have to deallocate (release) img by your own, because in this case cv::Mat won't do that for you. - image has to be 8 bpp. 2012/11/2 shari <[email protected]> > what if my image is IPlmage *img;then? > > how does the code modify? > > On Nov 2, 4:13 am, Andres <[email protected]> wrote: > > Here you have a snippet of that.
