Problems solved by technology

[0004] The feature extracted by the traditional character recognition method is usually a single feature, but for the Manchu alphabet, due to the particularity of the characters, only a single feature extraction does not have a certain noise anti-interference ability
Therefore, when the noise interference is large, the recognition rate of Manchu letters will be low

Abstract

A manchu handwritten recognition device, relating to a pattern recognition technology, using to solve the problem of, because of the particularity of the manchu, owning only a single feature without a certain degree of noise immunity, the keys of the technology are: a first dimension reduction module, which is configured to reduce module dimension of manchu eigenvalue by using LDA linear discriminant analysis method, so as that the eigenvalue of manchu can be obtained; a first classification module, which is configured to classify the manchu eigenvalue by using k-nearest neighbor method so as that the manchu alphabets of the manchu alphabet image can be obtained. The effects are: on the one hand, reducing the dimension and improving the classification efficiency, on the other hand, distinguishing more easily to the manchu alphabet after dimension reduction. The device has the advantages that better noise immunity can improve the rate of accuracy of manchu alphabet after dimension reduction by using k-nearest neighbor method.

Description

technical field [0001] The invention relates to the technical field of pattern recognition, in particular to a method and device for recognizing handwritten Manchu letters. Background technique [0002] As one of the ancient languages, Manchu is a very representative ethnic minority script. Research on the recognition method of ethnic minority characters is an important technical means to protect and inherit the cultural heritage of ethnic minorities, and has important social value and historical significance. At present, the handwriting recognition of Chinese characters has met the practical needs, and the offline handwriting recognition products of English and numbers are also very mature, but the handwriting recognition of punctuated Manchu is still a blank field and needs to be studied. [0003] The utility model patent with the authorized notification number CN 205451106 U discloses a handwritten Manchu alphabet collection system, that is, based on this patent, the coll...
