RESUMEN
The biological process of wound healing is one of the most complex occurrences during our lives turning a serious public health problem. The rate of healing chronic wounds in humans is relatively uniform, regardless of etiologies, and is estimated to be 0.63-0.65 mm/week for diabetics and non- diabetics [1], respectively, being visually unnoticeable throughout the daily care of a wound. A ruler designed for this purpose using a decal for setting the wound limits, however an area with a lot of irregularity requires a tool that carries out this measurement autonomously through image recognition, making the process feasible for the medical teams responsible for the treatment. The digitized images undergo morphological processes sing on the polygonal line that delimits the wound region. With the region delimited by the polygonal, the area and the perimeter are determined. A comparison with analytical methods demonstrates that this tool has the potential to become gold standard for estimating to estimate the area and the perimeter of wounds in the healing process.
