HSV images are made of HSV color combination, below matlab code extracts all these individual channels.
Example :
>> A = imread('penguins.jpg'); % reading Image >> B = rgb2hsv(A); >> AH = B(:,:,1); % extracting HUE Channel >> AS = B(:,:,2); % extracting SATURATION Channel >> AV = A(:,:,3); % extracting Value Channel >> figure, >> subplot(2,2,1); imshow(A); title('original image'); >> subplot(2,2,2); imshow(AH); title('HUE'); >> subplot(2,2,3); imshow(AS); title('SATURATION'); >> subplot(2,2,4); imshow(AV); title('VALUE');
