Embodiment Construction

[0039] Now in conjunction with embodiment, accompanying drawing, the present invention will be further described:

[0040] Construct Chinese characters in the training phase: train each Chinese character separately. In a character class, N images are randomly selected as training samples, and these N images are input into the Congealing algorithm based on fuzzy entropy for K iterations.

[0041] Specific steps are as follows:

[0042] (1) Initialize a transformation parameter vector for N training images respectively

[0043] v j =(t x ,t y ,θ,s x ,s y , h x ,h y)=0(j=1toN), then the corresponding transformation matrix U is calculated respectively by formula (4) j .

[0044] U j = F ( v j ) ...

Abstract

The invention relates to a Chinese character construction and recognition method based on the fuzzy entropy Congealing method. The image correction technology-Congealing method is applied to the issue of handwritten Chinese character recognition for the first time, the handwritten Chinese character recognition method based on the fuzzy entropy Congealing algorithm is put forward, and a high character recognition rate can be obtained through the method. The full-data-driven method is applied to the process of handwritten Chinese character recognition, and it is proven that the high recognition rate can be obtained.

Description

technical field [0001] The invention belongs to computer image processing, and relates to a method for constructing and recognizing Chinese characters, in particular to a method for constructing and recognizing Chinese characters based on a Congealing method based on fuzzy entropy. Background technique [0002] Handwritten Chinese character recognition methods have been widely studied in the field of machine learning and artificial intelligence. At present, handwritten Chinese character recognition methods are divided into online recognition and offline recognition. Among them, the research object of the offline recognition method is the separated and isolated handwritten Chinese character image, and the machine learning technology is used to classify the handwritten Chinese characters to be recognized into the correct category through the training and classification process. [0003] Due to the huge number of Chinese characters, various Chinese character structures, and di...
