Embodiment 1

[0025] Embodiment 1: A font recognition method based on image processing, by collecting TTC font files, extracting character feature vectors therefrom to build a font feature vector database, uploading the image form information and corresponding character text information of a single character by the user, using modern Cutting technology and character shape features, after specific grayscale and binarization processing on the image, character features are extracted and feature vectors are generated, and all characters in the database are the data of the character text information input by the user to calculate the font recognition degree, and finally Output the most recognizable font set by sorting.

[0026] The specific steps are:

[0027] Step0.1: Collect TTC font files. The TTC font files include but not limited to Arial, HeiTi, Microsoft Yahei and more than 90% of existing fonts. The number of TTC font files is K;

[0028] Step0.2: Extract the image corresponding to each...

Abstract

The invention relates to a font recognition method based on image processing, belonging to the technical field of font recognition. As that TTC font file are collected, from which character feature vectors are extracted to form a font feature vector database, the image form information of a single character and the corresponding character text information are uploaded by a user, by using modern cutting technology and character shape features, graying and binarization are performed on the image specifically and then, the character features are extracted and the feature vectors are generated. The font recognition degree is calculated with the data of all characters input by users in the database, and the font set with the highest recognition degree is outputted through sorting. Compared withthe prior art, the present invention mainly solves the problems of poor accuracy and inflexible human-computer interaction when the prior art recognizes the font, and increases the accuracy and flexibility of the current font recognition relying on the computer.

Description

technical field [0001] The invention relates to a font recognition method based on image processing, belonging to the technical field of font recognition. Background technique [0002] Fonts are very commonly used in work, no matter what kind of document editor you use, fonts must be used. Fonts mean "when you use them, you hate less". In daily life, when browsing various websites, you often encounter many interesting fonts, but because you don't know what kind of fonts they are, you stagger with them. [0003] At present, there are already some font recognition websites on the Internet for people to use. The process usually starts with the user uploading the character image to be recognized, and pointing out the character information corresponding to the character image, and then recognizing and outputting it through the default recognition algorithm. , but the accuracy is not ideal. Simply put, the font recognition algorithm used in it is not very accurate. Contents of...
