When the wound boundary has been successfully determined
and thewound area calculated, we next evaluate the healing state
of the wound by performing Color segmentation, with the goal
of categorizing each pixel in the wound boundary into certain
classes labeled as granulation, slough and necrosis [21], [24].
The classical self-organized clustering method called K-mean
with high computational efficiency is used [22]. After the color
segmentation, a feature vector including the wound area size
and dimensions for different types of wound tissues is formed
to describe the wound quantitatively. This feature vector, along
with both the original and analyzed images, is saved in the result
database.
