Question

Hello good morning ,

What is a code to count the RGB pixel values in attached image?

Answer 1

Hey Zo,

I am not clear on what your objective is.

If you want to find the RGB values of pixels in the image then you can find the syntax here.

If you want to count how many pixels are there for each possible color combination you can run this script in Matlab -

A = imread('image.jpg')
b=size(A)
col=zeros(256,256,256);
 
for i=1:b(1)
    for j=1:b(2)
         col(A(i,j,1)+1,A(i,j,2)+1,A(i,j,3)+1)=col(A(i,j,1)+1,A(i,j,2)+1,A(i,j,3)+1)+1;
    end
end
