For RGB the pixel components take values between 0 and
255. For YCbCr the pixel components take values depending
on the component, Y has values between 16 and 235, Cb and
Cr are in the range [16 240]. For HSV the pixel components
take values between 0 and 1. For results evaluation we used a
set of 30 images representing cutaneous pigmented legions on
the body of the first author of the paper. The images used were
captured using a smartphone camera at a resolution of
4128x2322 in the same lighting conditions (day light). For
evaluation of resolution and lighting effects the images were
processed using Matlab functions.
