Abstract

The invention discloses an end-to-end-based variable-length text recognition method. The method comprises the steps of preprocessing an image to obtain a positioning image; positioning a text in the positioning image, and segmenting the text to obtain a text area; and identifying the text in the text area to obtain text information. The method is quick in response and good in use experience, and areliable solution is provided for text recognition of multiple pictures.

Description

technical field [0001] The invention belongs to the technical field of image recognition, and in particular relates to an end-to-end-based indefinite-length text recognition method. Background technique [0002] Humans' cognition and perception of external information comes from vision. Therefore, the collection and processing of visual information has always been an important means for human beings to understand the world and laws. Artificial intelligence technology, through the collection of visual information, scientific screening, comparison and analysis of graphic and image information, and then through algorithms (deep learning), understanding and thinking, the real reality content is presented in the computer. With the development of artificial intelligence and deep learning technology, the application of artificial intelligence technology in the field of vision has become increasingly prominent, and has received extensive attention and research. [0003] Nowadays, t...
