Abstract

The embodiment of the invention discloses a method and device for cutting a character and an electronic device. The method comprises the step of obtaining a current recognition result and at least one historical recognition result of a target area, wherein the current recognition result is a recognition result of a current frame image of the target area, the historical recognition result is a recognition result of a historical image of the target area, and the current recognition result and the historical recognition result respectively comprise at least one character block; the step of obtaining the confidence coefficients of the character blocks in the current recognition result and the character blocks in the historical recognition result and the positions of the character blocks in the current recognition result and the character blocks in the historical recognition result in the image; the step of obtaining the error cutting area in the current recognition result according to the confidence coefficient and the position of each character block. According to the method, the error cutting area of the current frame image is determined by combining the recognition results of the historical image in an auxiliary mode, and when the error cutting area is cut again, the blindness of cutting the current frame image can be reduced, and the cutting accuracy and cutting efficiency can be improved.

Description

technical field [0001] The present application relates to the technical field of image recognition, in particular to a character cutting method, device and electronic equipment. Background technique [0002] OCR (Optical Character Recognition, optical character recognition) refers to electronic equipment (such as scanners or cameras, etc.) to check characters on paper or other objects, determine their shapes by detecting dark and bright patterns, and then use character recognition methods to translate the shapes into The process of computer text; that is, the process of scanning text data, and then analyzing and processing image files to obtain text and layout information. [0003] At present, the character cutting technology of OCR mainly includes the character cutting technology based on recognition feedback. This technology first preprocesses the single frame image, including binarization, smoothing, denoising, etc., and then performs character cutting. The cutting resul...
