Title
(EN) MACHINE LEARNING ENABLED SYSTEM FOR SKIN ABNORMALITY INTERVENTIONS
(FR) SYSTÈME APTE À L'APPRENTISSAGE AUTOMATIQUE POUR INTERVENTIONS SUR ANOMALIES DE PEAU
Abstract
(EN) Systems and methods for use in classifying and measuring images of skin abnormalities. The systems and methods can be used in an AR enabled system that may be used to assist in skin surgeries and skin abnormality triaging and diagnosis. The system uses a convolutional neural network to classify a skin abnormality in an initial image. The CNN may also be used in determining the boundaries of the skin abnormality. A fiducial marker may be present in the initial image and this marker may be used in automatically measuring the size of the skin abnormality. An adjusted image is generated based on the measured abnormality and this adjusted image can be used as an overlay in an AR enabled system for use in assisting surgical procedures.
(FR) L'invention concerne des systèmes et des procédés destinés à être utilisés dans la classification et la mesure d'images d'anomalies de peau. Les systèmes et procédés peuvent être utilisés dans un système apte à l'AR qui peut être utilisé pour aider à la chirurgie de la peau et au triage et diagnostic d'anomalies de peau. Le système utilise un réseau neuronal convolutif pour classifier une anomalie de peau dans une image initiale. Le CNN peut également être utilisé dans la détermination des limites de l'anomalie de peau. Un marqueur de repérage peut être présent dans l'image initiale et ce marqueur peut être utilisé pour mesurer automatiquement la taille de l'anomalie de peau. Une image ajustée est générée d'après l'anomalie mesurée et cette image ajustée peut être utilisée comme calque dans un système apte à l'AR en vue d'une utilisation dans l'aide aux procédures chirurgicales.
