image processing - a color histogram algorithm in matlab -


i'm trying write code of article name vsumm.
i'm stopped in 1 step of coding , not know if i'm write or not!?
acoording article:
in vsumm, color histogram algorithm applied hsv color space, popular choice manipulating color.the hsv color space developed provide intuitive representation of color , near way in humans perceive , manipulate color. vsumm color histogram computed hue component, represents dominant spectral component color in pure form (manjunath et al., 2001). moreover, quantization of color histogram set 16 color bins, aiming @ reducing amount of data without loosing important information. color bins value established through experimental tests (see avila et al., 2008b).
step i've done this,is correct:

b=imread('pics\1.jpeg'); hsv = rgb2hsv(b); h = hsv(:,:,1);

yes, looks good. however, use imhist instead of hist.
