Embodiment Construction

[0060] Please refer to figure 1 , which displays a file 10 containing pictures and text. Such as figure 1 As shown, the document 10 includes a picture part 100 and a text part 200 . The picture portion 100 includes a pattern and the text “WELCOME” on the pattern, while the text portion 200 is composed of a plurality of characters T.

[0061] The image-text separation method of the present invention is to identify the picture part 100 and the text part 200 of the document 10 . The text enhancement method of the present invention is to enhance the image of the text portion 200 after the image-text separation is completed, so as to make the text in the text portion 200 and the picture portion 100 clearer.

[0062] The details of the image-text separation method of the present invention are described below. see Figure 2A with Figure 2B ,Such as Figure 2A As shown, the image-text separation method of the present invention mainly divides the image of the document 10 into m...

Abstract

The present invention provides a text-picture separating method and a text enhancing method. The text-picture separating method is used for separating a picture part and a text part of an image, and comprises a rough classification step, a progressive classification step and a text-on-picture detection step. The text enhancing method is used for enhancing the text part in the image comprising the picture part and the text part, and comprises the following steps: a. a text-picture separation step for separating the picture part and the text part, comprising that the picture is cut into a plurality of lines and each line is cut into a plurality of segments which are classified into picture segments and text segments; b. a text enhancing step comprising that the text segments are sharpened to enhance the contrast grade of the text segments. The text-picture separating method and the text enhancing method carry out brightness adjustment on the obtained text part so as to enhance the image of the text part.

Description

technical field [0001] The invention relates to a method for image-text separation and text enhancement. Background technique [0002] A multifunctional business machine is a commonly used digital image processing device at present, which provides functions such as image scanning and printing. In multi-function business machines, image-text separation and text enhancement processing are commonly used image processing technologies. [0003] A general file image mostly contains two parts, pictures and text, and the picture and text in the image can be distinguished through the image-text separation technology for further processing. For example, in the case where image-text separation is not performed, when printing a document, the printer will use a color ink cartridge composed of multiple colors to print the entire document image, that is to say, even the text part will be printed using a color ink cartridge, In terms of ink usage efficiency, using color ink cartridges com...
