If you want hue and saturation, then what you need is to transform from RGB to HSV, try rgb2hsv.

"I want to get the values of CMYK for each images using"
One way: If the imahes is RGB, then youn can use the following to get the CMYK
C= 255-Red_component;
M= 255-Green_component;
Y= 255-Blue_component;
C=cmyk_image(:,:,1);
M=cmyk_image(:,:,2);
Y=cmyk_image(:,:,3);
K=cmyk_image(:,:,4);
Here loop may issue here, its FAQ to call images one by one and do processing
images=
for i=1:length(images)
im_data=imread(' ')
%RGB2CMYK
% Extract CMYK data
end
