METHOD FOR RECOGNITION OF TEXT IN IMAGES OF DOCUMENTS Russian patent published in 2022 - IPC G06K9/62 G06T7/10 G06N3/02 

FIELD: computing technology.

SUBSTANCE: computer-implemented method for automatic recognition of text in an image of a document, the method is executed on a computing apparatus containing a processor and a memory storing instructions executed by the processor and containing stages of: obtaining an image of the document; isolating an area of the document in the image; based on the isolated area of the document in the image, classifying a type of the document using a convolutional neural network; binarising the image of the determined type of document in order to separate the text of the document from the background; segmenting the image of the document, with the determined type of document, in order to determine text fields, by determining the coordinates of the bounding rectangles of fields; determining the type of found text fields using structural document templates; conducting text recognition on the identified text fields; validating the recognised text on the identified text fields based on a set of rules related to the data contained in the fields and the expected presentation formats of said data.

EFFECT: increase in the accuracy of extracting information from images of documents.
