Problems solved by technology

[0003] At present, it can be judged whether the two image files are consistent by comparing the MD5 value or binary value of the two image files. However, when only the format of the image file changes, it will cause the MD5 value and binary value to change. The accuracy of similarity judgment is low

Abstract

The invention discloses an image similarity determination method and device and electronic equipment. The method comprises the steps: calculating the peak signal-to-noise ratio of a to-be-determined image according to the mean square error of the to-be-determined image and a standard image; And if the peak signal-to-noise ratio of the to-be-determined image is smaller than a peak signal-to-noise ratio threshold value, determining the similarity of the to-be-determined image relative to the standard image according to at least one of the brightness similarity, the contrast similarity and the composition similarity of the to-be-determined image relative to the standard image.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a method, device and electronic equipment for determining image similarity. Background technique [0002] The development of Internet technology has enabled mass dissemination of image data. In the process of mass dissemination of image data, it is easy to form a large number of identical images. Too many identical images cause waste of storage space. Accurate identification of identical images is conducive to subsequent image processing. [0003] At present, it can be judged whether the two image files are consistent by comparing the MD5 value or binary value of the two image files. However, when only the format of the image file changes, it will cause the MD5 value and binary value to change. The accuracy of similarity judgment is low. Contents of the invention [0004] Embodiments of the present application provide a method, device, and electronic device for det...
