Abstract

The embodiment of the invention discloses a 2D image text detection method based on Chinese character stroke features. The 2D image text detection method is used for solving the problem that in the prior art, a method for extracting the stroke features from a grey-scale map is used for extracting the Chinese character stroke features in a color image, and the detection accuracy is low. The method comprises the following steps: receiving a 2D image to be detected; carrying out edge analysis on the 2D image; and extracting Chinese character strokes in the 2D image according to an edge analysis result. According to the method, interference data caused by data fluctuation in the color image can be removed, the range of Chinese character extraction is widened, and the accuracy of Chinese character stroke recognition in the color image in natural scenes such as indoor and outdoor scenes can be improved.

Description

technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to a 2D image text detection method based on stroke features of Chinese characters. Background technique [0002] Chinese character recognition is one of the main ways to input Chinese characters into computers by using computers to automatically recognize Chinese characters. Chinese character recognition is a branch of pattern recognition. Chinese characters are a special mode, which is characterized by a large number of characters, complex glyphs, and some very similar glyphs. Printed Chinese characters have a variety of fonts (imitation Song, Song, Hei, regular script and print, etc.) and a variety of sizes. font size. Therefore, Chinese character recognition is a rather difficult problem. There are two basic methods of Chinese character recognition: statistical method and structural method. Chinese characters are composed of strokes, which have a strict ...
