Hi :) I'm searching for a function wich is able to get the BGR data of any pixel (with the X/Y coordinates of this pixel) and change it. Do you know something about a function like that? I program in C++.

Best regards, Evoxz

Mat img=imread("<<filename>.<extension>>",CV_LOAD_IMAGE_COLOR);

int i=;//row pixel co-ordinate;
int j= ;//coloumn pixel co-ordinate;
Vec3b intensity = img.at<Vec3b>(i,j);
float blue=intensity.val[0];
float green=intensity.val[1];
float red=intensity.val[2];
