When i read a grayscaled image using for example in Opencv 2.3:
Mat src = imread("44.png" ,0);
How can i access the pixel value of it?
I know if its RGB i can use:
std::cout << src.at<cv::Vec3b>(i,j)[0].
Thanks in advance.
Since a grayscale image contains only one component instead of 3, the resulting matrix/image is of type CV_8UC1
instead of CV_8UC3
. And this in turn means, that individual pixels are not 3-vectors of bytes ( cv::Vec3b
) but just single bytes ( unsigned char
or OpenCV's uchar
). So you can just use:
src.at<unsigned char>(i, j)
