Abstract

The disclosure provides a formula recognition method, device, electronic equipment and storage medium. The method includes: acquiring an image to be recognized that contains a formula; identifying the tree structure of the formula based on a decoder network to obtain nodes of the tree structure; determining the type of the next node, wherein the next node is passed A node obtained by parsing the current node; in response to determining that the type of the next node is a structural node, based on the structural branch of the decoder network, determining the root node of the subtree included in the structural node; based on the subtree A root node of the tree, determining one or more sub-nodes included in the sub-tree; determining a target formula based on the one or more sub-nodes included in the sub-tree. As a result, the accuracy of formula recognition can be improved.

Description

technical field [0001] The present disclosure relates to the technical field of artificial intelligence, and in particular to a formula recognition method, device, electronic equipment and storage medium. Background technique [0002] With the popularity of online teaching, there are more and more applications for formula recognition. In the formula recognition scene, most users use mobile phones, tablet computers and other electronic devices to take pictures of the formulas to be recognized to obtain images to be recognized. In some scenarios, the formulas to be recognized may be handwritten, and the recognition of handwritten formulas is more complicated due to the different writing methods or writing styles of the writers. At present, there are schemes for recognizing handwritten formulas, but the recognition accuracy of these schemes is low and needs to be improved. Contents of the invention [0003] According to an aspect of the present disclosure, a formula recogni...
