Capsule endoscopy video-based Crohn disease automatic diagnosis system

The invention discloses an automatic Crohn disease diagnosis system based on a capsule endoscopy video, and the system obtains a whole-course video through a video obtaining module, carries out the classification of the whole-course video through a small intestine video recognition module, extracts a small intestine video in a target video, and carries out the classification of the whole-course video. The small intestine lesion detection module is used for carrying out feature extraction on each video frame in the small intestine segment video to determine the lesion probability in each video frame, the target video frame extraction module is used for averagely dividing the small intestine segment video into a plurality of segments of video, and for each segment of video, the plurality of video frames with the highest lesion probability in the video are extracted into a plurality of video frames with the highest lesion probability in the video; and determining a diagnosis result of the Crohn's disease through
