“…There are also improved methods with a slightly more complex formula for calculating the area of wounds with an elliptical form (Jansen, S., Rachel, K. 2016). Importance of this topic is mentioned and proved in papers "Computer software for vulnerometry" (Lukavetskyi, O., et al ,2017) and "Implementation features of wounds visual comparison subsystem" (Jaworski, N. et al, 2018) where, topic from medical point of view and computer program for calculation of wounds area are described. This program adds user an ability to encircle wound on image, using computer mouse, after that, wound area is calculated automatically.…”
