Abstract
Ulcers on legs and feet usually require long-term clinical treatment and follow-up. To facilitate the monitoring, we propose a fully automatic and low-cost method for ulcers detection and analysis. The ulcer segmentation is performed using an automatic processing based on pixel’s classification into background or not background classes. Features used to perform the classification are the values of three channels that define each pixel in the RGB color map and in the HSV color map.
We tested the algorithm on a dataset of 92 images, acquired from 14 different patients. The segmentation performances were evaluated in terms of overlap, recall and precision, by comparing the automatic segmentation with the manually one. The results show good average values of overlap, recall and precision.
Then, a Self-Organizing Map (SOM) was used for tissue classification. The SOM was trained in order to identify six colorimetric classes associated to different type of tissues.
