Image recognition system and image recognition method

The invention provides an image recognition system and an image recognition method, and relates to the technical field of image processing. The method comprises the following steps: acquiring a to-be-processed monitoring video sent by video monitoring terminal equipment; for every two monitoring video frames in multiple monitoring video frames included in the to-be-processed monitoring video, determining a video frame association degree between the two monitoring video frames; based on the video frame association degree between every two monitoring video frames in the multiple monitoring video frames included in the to-be-processed monitoring video, each monitoring video frame in the multiple monitoring video frames included in the to-be-processed monitoring video is recognized, and a video frame recognition result corresponding to each monitoring video frame is obtained, the video frame recognition result is used for representing the probability that the illegal behavior information exists in the correspondi
