Problems solved by technology

[0004] However, due to the large difference between the bill image and the object image, and the style of the bill image uploaded by the user, the shooting scene of the bill image, and the shooting angle vary widely, the traditional object image classification technology cannot handle the classification of the bill image well. thereby reducing the accuracy of ticket image classification

Embodiment Construction

[0043] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0044] The bill image classification method provided by this application can be applied to such as figure 1 In the illustrated application environment, the application environment involves a terminal 102 and a server 104 . Wherein, the terminal 102 communicates with the server 104 through the network. The terminal 102 can be, but not limited to, various personal computers, notebook computers, smart phones, tablet computers and portable wearable devices, and the server 104 can be realized by an independent server or a server cluster composed of multiple servers.

[0045] When the terminal 102 rece...

Abstract

The present invention is applicable to the technical field of computer vision, and provides a bill image classification method, device, computer equipment and storage medium. The method includes: sampling the bill image to be classified to obtain a plurality of bill images of different scales; using a sliding window Scan each bill image separately, and extract the image semantic information of each image after scanning to obtain the single-scale image semantic information; fuse the information of each single-scale image semantic information to obtain the multi-scale image semantic information; according to the multi-scale image semantic information The information is used to classify the bills, and the bill types of the bill images to be classified are obtained. Adopting this method can improve the accuracy of bill classification.

Description

technical field [0001] The invention belongs to the technical field of computer vision, and in particular relates to a bill image classification method, device, computer equipment and storage medium. Background technique [0002] Institutional industries such as banking, finance and insurance involve a large amount of bill data processing, such as: train tickets, motor vehicle invoices, itineraries, value-added tax invoices, etc. The traditional bill data processing method is to manually check the bill image data submitted by the user, and enter it into the bill management system manually. Since the whole process of processing is done manually, it not only consumes a lot of manpower and material resources, but also has low processing efficiency. [0003] With the rapid development of science and technology, in order to reduce consumption and improve processing efficiency, automated bill data processing technology has emerged. To realize the automatic processing of bills, t...
