Healthcare treatments might benefit from advances in artificial intelligence and technological equipment such as smartphones and smartwatches. The presence of cameras in these devices with increasingly robust and precise pattern recognition techniques can facilitate the estimation of the wound area and other telemedicine measurements. Currently, te...

... Wound assessment largely depends on evaluating the visual elements of the wound, such as the amount of surrounding erythema, the presence and color of granulation tissue, wound drainage, and accurately measuring the key dimensions of the wound to calculate the wound area and volume. These processes are typically accomplished by traditional methods, such as a photographic image of the wound using a digital camera, a paper-ruler, and a depth probe to determine the key measurements of the wounds [7]. However, using these traditional methods in daily practices is not ideal [8], especially when measuring irregular wound boundaries [9,10], or unequal distances from the edge of the wound [11]. ...
... Existen varios espacios de color para examinar y aprovechar la información presente en una imagen digital y, aunque el espacio de color RGB es el más utilizado, cada modelo tiene un campo específico de trabajo y fortalezas [8]. Para el desarrollo de algoritmos de PDI orientados a tratar lesiones en la piel se prefieren modelos, como el HSV, que describen el color de forma análoga a como lo percibe el ojo humano, donde la crominancia es más importante que la percepción global del color. ...
