Method for identifying handwritten Uigur characters

A technology of character recognition and handwriting, which is applied in character and pattern recognition, instruments, computer parts, etc., can solve the problems that Uyghur word recognition cannot be applied, and the recognition method of handwritten Uyghur 128 characters has not been reported in relevant literature, so as to reduce the characteristics Complexity and number of categories, small feature dimension, and the effect of improving the recognition rate

Problems solved by technology

However, the Uyghur 41 types of characters only contain the single-vertical and simple single-vertical forms of Uyghur 32 letters, which cannot be applied to Uyghur word recognition based on character segmentation
[0004] At present, there are no relevant literature reports on the recognition method for 128 types of Uyghur handwritten characters

Embodiment Construction

[0038] The handwritten Uighur character recognition method of the present invention is based on 128 types of Uyghur characters, and the 128 types of handwritten Uyghur character sets refer to figure 1 . The method of the present invention is divided into three parts, and the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0039] The first part is the establishment of the Uygur character component dictionary and the handwritten Uyghur character component library; the establishment of the Uyghur character component dictionary. For each Uyghur character, its main part can be regarded as a component, called the main component, and the additional part is divided into three parts according to whether the stroke is dotted or not. Point components and additional components. In addition, in order to unify the model, set an empty component, which means that there is n...

Abstract

The invention discloses a method for identifying handwritten Uigur characters, which belongs to the field of character mode identification and can effectively identify 128 classes of handwritten Uigur characters in real time. The method comprises the following three parts of: (1) establishment of a Uigur character component dictionary and a handwritten Uigur character component library; (2) a character training process, comprising character one-line information acquisition, character pre-processing, component partition during training, extraction of time division direction characteristics, calculation of training characteristics of components and the like; and (3) a character identification process, comprising character one-line information acquisition, character pre-processing, componentpartition during training, extraction of time division direction characteristics and point component characteristics, characteristic fusion of components, identification result output and the like. The method is the basis for identifying whole Uigur words. By using the method and a handwritten Uigur word splitting method, a user can freely, naturally and smoothly write the Uigur words at random angle in a mobile platform handwriting frame such as an intelligent mobile phone and the like, and the method can realize robust identification.

Description

technical field [0001] The invention belongs to the field of character pattern recognition in pattern recognition, specifically to the field of handwritten character recognition, and is used for recognizing handwritten Uighur characters input by mobile terminals. Background technique [0002] The Uyghur script belongs to the West-Hungary branch of the Turkic language family of the Altaic language family, and is the language of the Uyghur minority, an important ethnic minority in my country. The current Uyghur language consists of 32 letters. According to the position in the word, each letter has 2-8 writing forms such as front-joint, double-joint, back-joint, single vertical, etc., and has evolved into 124 characters. Uighur words are composed of one or more characters, including 124 types of alphabetic variant characters, two compound characters, a trailing prefix character and a middle prefix character, a total of 128 characters. The characters in a word are connected alo...
