Abstract

The invention relates to an nvoice seal removing method, device and computer storage medium. The method comprises the following steps: collecting invoice image samples containing seal patterns, forming a data set, training the data set to obtain a trained detection model; detecting an invoice image to be sealed by using the trained detection model, extracting a seal region image in the invoice image, and determining a color of the seal pattern; Removing the seal in the seal area image according to the color of the seal pattern to obtain a seal area background image; the background image of theseal area is fused with the invoice image after the seal area image is extracted to obtain a target invoice image with the seal eliminated. The method for eliminating the invoice seal of the invention can better eliminate the seal, avoid influencing the identification of other text information in the invoice, obviously improve the accuracy of the invoice identification and improve the working efficiency of the invoice identification.

Description

technical field [0001] The invention relates to the technical field of invoice identification preprocessing, in particular to a method, device and computer storage medium for eliminating an invoice stamp. Background technique [0002] In recent years, with the rapid development of my country's social economy, economic activities have become increasingly frequent, and both ordinary consumers and various types of enterprises have become more and more aware of the fact that consumption must be invoiced and reimbursed by the ticket. At present, hundreds of millions of invoices are used for reimbursement in my country every year, and the types of invoices are also increasing. If these invoices are manually processed, on the one hand, it will consume a lot of manpower and material resources, increase the workload of the financial personnel responsible for reimbursement, and take up a lot of extra energy for the reimbursement person. On the other hand, manual processing of invoice...
