Abstract

The invention provides an image comparison method, an image comparison device, electronic equipment and a medium. The image comparison method comprises the steps of acquiring a to-be-detected seal image, and acquiring a reserved seal image corresponding to the to-be-detected seal image; obtaining a rotation angle of the to-be-detected seal image relative to the reserved seal image; obtaining the overlap ratio of the to-be-detected seal image and the reserved seal image under the rotation angle; and determining the authenticity of the to-be-detected seal image based on the overlap ratio.

Description

technical field [0001] The present disclosure relates to the technical field of computers, and more specifically, to an image comparison method, an image comparison device, electronic equipment and media. Background technique [0002] In many enterprises, it is common to need to compare images of a specific object to determine whether the image of the specific object is real and valid. For example, in order to verify the authenticity of the seal in the contract, it is necessary to compare the seal in the contract document with the seal in the corresponding reserved original. The seal comparison method generally adopts the method of manual review and comparison. Moreover, the same company may have multiple seals (such as official seals, special seals for contracts, special financial seals, etc.), and the company may also replace a new seal. [0003] In the process of realizing the disclosed concept, the inventors have found at least the following problems in the prior art: ...
