Claim:
1. A system for polyp detection using optical colonoscopy images, the system comprising: an input configured to receive a series of optical images acquired from a subject; a processor configured to process the series of optical images with steps comprising: i. receiving an optical image from the input; ii. constructing an edge map corresponding to the optical image, the edge map comprising a plurality of edge pixels; iii. generating a refined edge map by applying a classification scheme based on patterns of intensity variation to the plurality of edge pixels in the edge map; iv. identifying polyp candidates using the refined edge map; v. computing probabilities that identified polyp candidates are polyps; vi. generating a report, using the computed probabilities, indicating detected polyps; an output for displaying the report; wherein the processor is further configured to apply a Canny technique on multiple color channels of the optical image; and apply a tensor voting technique to identify polyps.
