Abstract

A method for automated discrimination between Group A Streptococcus (GAS) and non-GAS pharyngitis, including segmenting and tracking a region of interest including a throat in a displayed image or video; automatically acquiring an input image based on the segmentation of the displayed image or video; receiving at least one patient symptom; removing shadows in the input image; segmenting the input image to isolate the region of interest including the throat; determining an image quality of the isolated region of interest; and classifying, via a machine learning classifier, pharyngitis in the isolated region of interest as being caused by GAS or a non-GAS cause based on the isolated region of interest and the at least one patient symptom.
