Abstract

The invention discloses a text image processing method, which comprises the following steps: when a text image processing request is received, obtaining a text image corresponding to the text image processing request, and carrying out horizontal correction on the text image; when the horizontal correction of the text image is completed, obtaining a target pixel band in the text image; processing the target pixel band through a preset Gaussian mixture model, and judging whether an intersection region intersected with text strokes in the text image exists in the target pixel band or not; and ifthe target pixel band has the cross region, taking the target pixel band except the cross region as an interference line, and deleting the interference line in the text image. The invention further discloses a text image processing device and equipment and a storage medium. According to the invention, the accuracy of deleting the interference line in the text image is improved, and the deletion ofwriting strokes is effectively avoided.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to a text image processing method, device, equipment and storage medium. Background technique [0002] With the rapid development of computer recognition technology, the application field of optical character detection and recognition technology is becoming wider and wider. Optical character detection removes the noise in the text image. In the process of removing the noise of the text image, the text strokes will be broken and missing. [0003] The current text image noise removal can be classified into two types; the first type is based on color features: according to the color difference between the interference line and the text character, the interference line is separated from the text image, so as to achieve the purpose of removing the interference line. The method can well remove the interference lines that are quite different from the text color information; when the...
