Abstract

The invention provides a character enhancement method and device. The method comprises the steps of conducting shading detection on a document according to a preset shading template; dividing pixel points in the document according to a shading detection result to obtain a shading area and a character area; conducting recognition in a black-character-on-a-white-background mode or a white-character-on-a-black-background mode on the pixel points in the character area; conducting character enhancement processing on the pixel points in the black-character-on-a-white-background mode or the white-character-on-a-black-background mode obtained through recognition, and obtaining a document after character enhancement processing. According to the character enhancement method and device, effective recognition of shading in the document is achieved, through character enhancement processing on characters in the black-character-on-a-white-background mode or the white-character-on-a-black-background mode of which the shading is removed or weakened, the presentation definition of the characters in a printed document is improved.

Description

technical field [0001] The invention relates to image processing technology, in particular to a text enhancement method and device. Background technique [0002] The so-called text enhancement refers to making the text in the printed document appear more clearly. [0003] In the prior art, the processing method for enhancing the text in the printed document is to first separate the non-overlapping images and text in the document, and then enhance the text; or adjust the display brightness of the entire document to highlight the text the goal of. [0004] However, if the above-mentioned method of the prior art is used to process a document with black characters on a white background and / or white characters on a black background, the text is easily disturbed by the shading. figure 1 Examples are given to illustrate the presentation forms of various shading. Therefore, for documents with black characters on a white background and / or white characters on a black background wit...
