Method and device for eliminating invoice seal, storage medium and computer equipment

Abstract

The invention relates to a method and device for eliminating an invoice seal, a storage medium and computer equipment. The method comprises the steps: acquiring an invoice image; inputting the invoiceimage into a multi-task network model comprising a first branch and a second branch, and performing convolution on a target channel part of the invoice image through the first branch to obtain a target channel feature map; carrying out convolution on the invoice image through the second branch to obtain a global feature map; fusing the global feature map and the target channel feature map to obtain a fused feature map; and performing deconvolution operation on the fusion feature map to obtain an invoice image after the seal is eliminated. According to the scheme provided by the invention, thesituation that the text covered by the seal is also eliminated in the seal eliminating process can be avoided, so that the situation that the text information in the invoice is missing is avoided, and the recognition accuracy of the text information in the invoice is improved.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular to a method, device, storage medium and computer equipment for eliminating invoice stamps. Background technique [0002] When the invoice is entered into the system, it is generally necessary to check the invoice information entered into the system, and a large amount of labor costs will be invested in the manual verification method; while the machine verification is used, the invoice needs to be identified first, because the invoice in the invoice Stamps often cover important textual information, which interferes with the identification of invoices. [0003] In the traditional stamp removal scheme, the invoice image is usually converted from RGB color space to HSV or other color space, and then the red area is extracted, and then the red area is filled with the nearest background color to achieve the effect of stamp elimination. However, in the above solution, t...
