Non-intrusive assessment of pressure injuries using Artificial intelligence and computer vision

Pressure injuries represent a major concern in many nations. Disabled and elderly people are highly affected by this fast-growing disease. A continuous assessment of pressure injuries is crucial for an efficient treatment. If retrieving quantitative information using invasive methods is considered to most used method, it remains painful to the patients and may also increase the risk of infections. Hence, developing non-intrusive methods for the assessment of pressure injuries would represent a highly useful tool for caregivers and a relief for the patients. Combining sensors information, image processing techniques and artificial intelligence represent a promising solution for this challenge. The main outputs of the designed system are: real measurements (area, volume, depth and perimeter), tissue types present in the wound, temperature and the presence of infection. Data collection represents a paramount step for the achievement of accurate results, as deep learning models require a large number of data to learn the underlying features. Then, imparting 3D reconstruction using stereo matching with DL models for the segmentation and classification of tissue types will enable the user to extract all the useful information about the pressure injury and hence track its healing.
