Embodiment 1

[0039]OCR has received extensive attention and applications in various industries such as education, finance, medical care, transportation, and insurance. With the improvement of office electronization, documents originally stored in paper form are gradually passed through electronic means such as scanners. Save as an image instead. In order to be able to query or retrieve images of specified records, it is necessary to index images and image content data. In order to establish an index, the scanned images are generally classified by OCR (Optical Character Recognition, Optical Character Recognition) technology, and then recognized to obtain its content.

[0040] When the existing OCR technology is used for form recognition, the main technical means used when performing binary processing on images generally include: global threshold method, local threshold method, region growth method, waterline algorithm, minimum description length method , methods based on Markov random fiel...

Abstract

The invention provides a table recognition method and device and electronic equipment, relates to the technical field of artificial intelligence, in particular to the technical field of deep learning and computer vision, and can be applied to an optical character recognition scene. According to the specific implementation scheme, a to-be-recognized image is obtained, and the content displayed in the to-be-recognized image comprises a to-be-recognized table; segmenting and merging a to-be-recognized table in the to-be-recognized image to obtain a merging result, and performing optical character recognition processing on the to-be-recognized table to obtain a first recognition result; and carrying out matching processing on the combination result and the first identification result to obtain a second identification result. The technical problem that in the prior art, table recognition accuracy in an image is low is at least solved.

Description

technical field [0001] The present disclosure relates to the technical field of artificial intelligence, in particular to the technical field of deep learning and computer vision, which can be applied to optical character recognition scenarios, and specifically relates to a form recognition method, device and electronic equipment. Background technique [0002] With the improvement of the degree of office electronization, documents originally stored in paper form are gradually converted to image form through electronic means such as scanners. In the prior art, complex image processing procedures are usually used to identify tables in images. On the one hand, the image processing algorithms used are complex, and the cost of time and space is high. Forms with uneven or blurred backgrounds cannot be recognized accurately, reducing the accuracy of recognizing forms in the image. Contents of the invention [0003] The disclosure provides a form recognition method, device and el...
