Description of the WLPolyp-UCdb

· WLPolyp-UCdb is a database containing images that display colonic polyps, as well as, normal colonic mucosa. It was generated from 42 different colonoscopy short videos, of 42 different patients, recorded with a White Light (WL) video colonoscope, by medical doctors from the Faculty of Medicine of the University of Coimbra, Portugal.

· Polyp frames: there is a total of 1680 instances of 42 different polyps (40 images per polyp, obtained by sampling each video every 10 frames).

· Normal frames: there is a total of 1360 images displaying normal colonic mucosa.

· The images are RGB color images with 576x720 pixels (per color channel).

Description of the folders

· There are 2 folders named Polyp and Normal.

· The Polyp folder contains 42 subfolders corresponding to images extracted from the 42 videos: inside each subfolder there are 40 polyp images (40x42=1680 polyp images).

· The Normal folder contains the 1360 normal colonic mucosa frames.
