As a contour splitting algorithm, drop-fall algorithm has shown good performance. However, it is defective in locating the start of the algorithm and the seeping process in vertical direction inside character stroke block. To solve these problems, an improved drop-fall algorithm is proposed in this paper, where a main point is cited to determine the location of start point. Meanwhile, the dripping...
In this paper, we study oracle character recognition and general sketch recognition. First, a data set of oracle characters, which are the oldest hieroglyphs in China yet remain a part of modern Chinese characters, is collected for analysis. Second, typical visual representations in shape- and sketch-related works are evaluated. We analyze the problems suffered when addressing these representations...
Local Binary Pattern (LBP) is a powerful texture descriptor for its tolerance against illumination changes and its computational simplicity. The basic LBP encodes 256 feature patterns in a 3×3 neighborhood, but not all the patterns are effective for classification. In this paper, we propose a simplified LBP(S-LBP) which produces optimal patterns by using the best coding principle for classification...
In this paper, we present a large scale offline handwritten Chinese character database-HCL2000 which will be made public available for the research community. The database contains 3,755 frequently used simplified Chinese-characters written by 1,000 different subjects. The writerspsila information is incorporated in the database to facilitate testing on grouping writers with different background such...
Low-resolution Chinese character recognition of vehicle license plate is always a difficult problem. On the basic of existing local binary patterns(LBP) operator, we propose a powerful and low-computation advanced LBP(ALBP)operator as feature extraction, and apply into Chinese character recognition for the first time. As local feature extraction operater, it produces a feature excursion for characters...
In this paper, we propose a new method to model the manifold of handwritten Chinese characters using the local discriminant projection. We utilize a cascade framework that combines global similarity with local discriminative cues to recognize Chinese characters. We find the similarity of different characters using a nearest-neighbor (NN) classifier, and followed by the Local Discriminant Projection...
Decoding based on the maximum a posterior probability (MAP) decision rule is usually used in mandarin large vocabulary continuous speech recognition, and the recognition results has the minimum sentence error rate. But word error rate (WER) is commonly used performance measure, so the decoding method based on the minimum Bayes risk decision rule has been proposed for optimizing the word error rate...
