Cascade analysis for intestinal contraction detection

摘要

A method and system cascade analysis for intestinal contraction detection is provided by extracting from image frames captured in-vivo. The method and system also relate to the detection of turbid liquids in intestinal tracts, to automatic detection of video image frames taken in the gastrointestinal tract including a field of view obstructed by turbid media, and more particularly to extraction of image data obstructed by turbid media.

主权项

1. A method for automatic assessment of contractile activity in a gastrointestinal (GI) tract, comprising:
identifying an image frame sequence, said image frame sequence comprising a plurality of frames from an image stream captured along the GI tract; detecting a lumen area in image frames of said image frame sequence; detecting a dynamic event in the image frame sequence, the dynamic event showing a specified dynamic pattern related to the detected lumen area; and classifying the image frame sequence as a candidate corresponding to an intestinal contraction.
