My Red and Blue values are wrong but all my green values are correct. It's pretty simple what i've done. What am I missing ? Please help

Answer 1

I use the first two loops to make a temporary copy of the image RBGTRIPLE tmpimage . The next two loops is used to locate each pixel and within it we then find the dimensions of the box, the subsequent two loops are used to traverse the values of the box and take their sum. Then we take the average of the sum with the cc and put the value back into the original image[i][j] for each color. But still I'm not getting the correct values, only green values are correct. What is it that I am missing?
