For texture characterization, we consider a set of features
derived from GLCM matrix: contrast (C), homogeneity (H),
mean (M), energy (N), and variance (V). Images are obtained
from Dermnet Skin disease atlas. Dermnet is the largest
independent photo dermatology source. Dermnet provides
information on a wide variety of skin conditions.
The proposed algorithm produce a skin map of a given image
and highlights patches of skin like pixels. The function reads
an image file given using Matlab command imread. A skin
map overlayed onto the image with skin pixels marked in
blue color is generated by using the GLCM matrix.
Following figures shows the output of the algorithm. Once
the skin pixels are extracted,, than it is easier to analyze the
skin diseases.
