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

The invention relates to a hand-written manchu alphabet identification system, belongs to the mode identification technology field and solves a problem that manchu alphabets only having one extracted single characteristic because of letter particularities have no noise interference prevention capability. The system is characterized by comprising a processing assembly (1202), wherein the processing assembly (1202) comprises one or more processors (1220) for instruction performing to accomplish steps of a manchu identification method. The method comprises steps that a K-neighbour method is employed to carry out classification processing on manchu alphabet characteristic values after dimension reduction, and manchu alphabets corresponding to to-be-identified manchu alphabet images are acquired. The system is advantaged in that on one hand, dimension reduction and classification calculation efficiency improvement are realized, on the other hand, the manchu alphabet characteristic values after dimension reduction are easier to distinguish, relatively good noise interference prevention capability is realized, and thereby accuracy of the manchu alphabets identified through employing the K-neighbour method according to the manchu alphabet characteristic values after dimension reduction is relatively high.

Description

technical field [0001] The invention relates to the technical field of pattern recognition, in particular to a system 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 collection of h...
