Description
technical field [0001] The embodiments of the present invention relate to the technical field of character recognition, and in particular to a method and device for character recognition of a mobile terminal. Background technique [0002] Optical Character Recognition (English full name is Optical Character Recognition, English abbreviation OCR) refers to the technology that electronic equipment converts the text on the picture into computer text output. In the optical character recognition process, there is a large computational task. If the OCR processing is performed on the mobile terminal, due to the limitation of the computing power of the mobile terminal, it takes a long time and the real-time performance is not strong. Contents of the invention [0003] Embodiments of the present invention provide a method and device for character recognition of a mobile terminal, aiming at solving the technical problems of long time consumption and low real-time performance in cha...
