Abstract

The invention provides a method and device for processing images. The method comprises the steps of obtaining the images to be recognized, wherein the images to be recognized comprise character images; carrying out edge cutting processing on the obtained images to obtain an effective range, containing the character images, of the images to be recognized; carrying out preprocessing on the images in the effective range of the images to be recognized to obtain the preprocessed character images; using multiple recognition engines to carry out recognition on the preprocessed character images; outputting a reliable recognition result when the recognition result of the preprocessed character images and at least one of the recognition engines is determined to be reliable. The method and device for processing the images can solve the problems that when image recognition is carried out, effective information in the images cannot be obtained accurately, and the recognition function is single.

Description

technical field [0001] The present application relates to the technical field of recognition, and in particular to an image processing method and device. Background technique [0002] In recent years, with the computerization of business, a large number of electronic documents are used, and for this reason, the importance of image recognition technology as a technology for converting paper documents into electronic documents is increasing day by day. [0003] In image recognition, due to the different shooting equipment used by the user, the size of the obtained image may be different. When the obtained image is recognized, the effective information in the image cannot be accurately obtained, and the effective information in the image Convert it into editable text information and provide it to the user. At the same time, the existing image capture device has a relatively single function and can only recognize and process one type of image, which cannot meet the actual needs...
