I = imread('peppers.png');
RedPlane = I(:,:,1);
GreenPlane = I(:,:,2);
BluePlane = I(:,:,3);
This how you may extract separate color planes in an RGB Image

Hi,
I have set my coding to C(im>=5.5 & im<6.5) = {uint8(cat(3,0,0,255))};
Is there any coding that can be use to count the number of pixel that belongs to the range of C(im>=5.5 & im<6.5)?
Thanks.
