How to know colour of each pixel in colour code format and want to store this colour code format in a text format

Question

I want to make a column and row of colour code of an camera image

Answer 1

Hi Ram, Do you want to extract the RGB color information of every pixel ? Are you using opencv libraries? If yes, then refer below code.

Mat m= imread("image.jpg");
for(int i=0; i<m.row;i++){
for (int j=0; j<m.col; j++){
std::cout <<" Pixel Position: "<< i<< j<<endl;
m(i,j) << Std: endl;
}
}

let me know, in case of any problem.
