MATLAB Image Processing: Getting HSV components from a colored image

Question

I am trying to get the hue, saturation and value images from an image (originally colored). I converted the image using the rgb2hsv() function but I am confused on how to get the component images.

Answer 1

As Matlab mentions, the output of rgb2hsv is returned as an m-by-n-by-3 image array whose three planes contain the hue, saturation, and value components of the image.Therefore you can simply get these components as:

hsv_image = rgb2hsv(rgb_image);
hue_component= hsv_image(:,:,1);
saturation_component= hsv_image(:,:,2);
value _component= hsv_image(:,:,3);
