Abstract

The invention discloses an image comparison method, a device, a video comparison method and a device. The invention is applied to the electronic device in order to determine the characteristic points of the two images to be compared. Under the condition that the number of characteristic points of the two images to be compared is greater than the first threshold, the number of the characteristic points which are matched in the two images to be compared is determined; under the condition that the number of the matched characteristic points in the two images is greater than the third threshold, the similarities of the two images are determined. The image comparison method has more accurate result than the fogged image which is mistakenly determined by other image comparison methods. The invention does not need the defogging processing, and thus the comparison efficiency is high. Because the video comparison method provided by the invention uses the image comparison method, whether the two videos are similar can be determined accurately and fast.

Description

technical field [0001] The invention relates to the field of image recognition, in particular to a picture comparison method and device, and a video comparison method and device. Background technique [0002] Network video is a dynamic image transmitted on the Internet in the format of WMV, RM, RMVB and MOV, including various film and television programs, such as self-made dramas, variety shows, videos, advertisements, etc., with large program capacity, diverse program types, It is popular for its simple storage and convenient receiving.
