Abstract

The invention discloses a text segmentation method and device, electronic equipment and a storage medium, and relates to the field of image processing. According to the specific implementation scheme, the method comprises performing binarization processing on a first grey-scale image containing a target text area to obtain a first binary image; performing morphological transformation on the first binary image to obtain a first mask image corresponding to the row contour of the target text area; performing mask processing on a first image containing a target text area by adopting the first mask image to obtain a line text area corresponding to each line of characters in the target text area; and segmenting the line text area corresponding to each line of characters to obtain character areas corresponding to each character in the target text area. According to the embodiment of the invention, automatic segmentation of the composition lattice text image can be realized.

Description

technical field [0001] The present application relates to the field of image processing, in particular to a text segmentation method, device, electronic equipment and storage medium. Background technique [0002] In the current image processing technology for text segmentation, it is usually line-based segmentation. For example, the segmentation of the table; the table includes multiple lines, and each line includes multiple characters. For composition lattice text, there is no corresponding segmentation method at present. Among them, the composition grid text refers to the text including horizontal and vertical frame lines, and each frame composed of horizontal frame lines and vertical frame lines contains at most one character such as a Chinese character. Contents of the invention [0003] The embodiment of the present application proposes a text segmentation method and device to realize the automatic segmentation of composition grid text. [0004] In the first aspect...
