The present invention concerns a device for producing a 'digital video classifier' configured to determine the quality of cleanliness of one or more segments of the digestive tube in a video capsule endoscopy (VCE) of a subject, comprising: a VCE allowing the acquisition of videos of segments of the digestive tube, video storage means, coupled with the VCE, an “image database” with images extracted from VCE exams, a “video database” with videos extracted from VCE exams, calculating means connected to the video storage means, and to the databases, and configured for performing a statistical learning for the generation of a “digital image classifier” from the “image database” and which classifies the images in adequate cleanliness or non-adequate cleanliness; generating the “digital video classifier” capable of classifying a video of a subject as being of adequate cleanliness or of non-adequate cleanliness of one or more segments of the digestive tube.

Device and method for producing a digital video classifier

A method for performing real-time detection and displaying of polyps in optical colonoscopy, includes a) acquiring and displaying a plurality of real-time images within colon regions to a video stream frame rate, each real-time image comprising a plurality of color channels; b) selecting one single color channel per real-time image for obtaining single color pixels; c) scanning the single color pixels across each the real-time image with a sliding sub-window; d) for each position of the sliding sub-window, extracting a plurality of single color pixels local features of the real-time image; e) passing the extracted single color pixels local features of the real-time image through a classifier to determine if a polyp is present within the sliding sub-window; f) real-time framing on display of colon regions corresponding to positions of the sliding sub-window wherein polyps are detected. A system for carrying out such a method is also provided.
