Hi, If you are using Matalab then hist(RGB) will calculate the histogram of individual components.Where RGB is 3 coulumn vector of R,G and B; Other way is divide the RGB space to cubes and calculte the hist taking each cube as bin.For this you can do suppose each component is 8 bits(A is image values [0 255]) G=A(:,:,1)+A(:,:,2)*2^(8)+A(:,:,3)*2^(16);%shift by 8 bits & 16 bits hist(G(:),10) will divide the cube into 10 bins regs gopal On Tue, 22 Oct 2002, Swetha wrote: > Hai, > > Is there any build-in function for Histogram for color images.?
