Abstract: A computer-implemented method, system, and computer-readable medium, for determining a pathologic condition from a medical image of a portion of a subject. The method includes acquiring a plurality of lesion locations in the medical image; applying a clustering algorithm to the plurality of lesion locations to identify at least one lesion cluster and corresponding lesion cluster data; categorizing each lesion cluster into one of a set of predetermined categories based on the identified lesion cluster data; applying at least one function to the lesion cluster data with regard to each category of the set of predetermined categories, wherein the at least one function provides a fixed number of data outputs; and determining a pathologic condition by processing the fixed number of data outputs of each category of the set based on a classification algorithm trained on image data defining medical images of the portion of a plurality of subjects.

Abstract: A computer-implemented method, system, and computer-readable medium, for determining a level of hypertension of a person. The method has steps of: acquiring image data defining a retinal image of a retina of the person that has been captured by a retinal imaging system; processing the image data to identify a plurality of vessel segments present in the retinal image; determining respective widths of vessel segments of at least a subset of the plurality of vessel segments present in the retinal image; and calculating, as a vascular summary metric, at least one average value or median value of the determined widths of the vessel segments present in the retinal image, to determine a level of hypertension by which the person has been affected.
