Embodiment Construction

[0034] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0035] Such as figure 1 , an online handwritten Chinese character stroke recognition method, its specific implementation steps are as follows:

[0036] 1. Establish a standard Chinese character stroke type coding library identified by the trend code set:

[0037] When recording the strokes of handwritten Chinese characters from the beginning to the end of the stroke, the plane coordinate system is divided into up, down, left, right, Eight directions of upper left, lower left, upper right and lower right, using eight Arabic numerals or other methods to represent the eight directions, and using the direction code to indicate the type of stroke, for complex strokes, split them into several independent strokes, by the strokes The direction codes are combined into stroke type codes. As "12345678" eight numbers represent eight trends, then the simple stroke "horizontal"...

Abstract

The invention discloses a stroke addition recognition method used when Chinese characters are handwritten on a digital handwriting platform in an online mode. The method specifically comprises the steps that a standard Chinese character stroke type code library identified with a direction code set is established; a tracing point set generated when a user handwrites Chinese characters in the online mode is recorded and is processed, and a record file of stroke type codes identified with the direction code set by the tracing point set is established; the stroke types of a current stroke and a prior stroke and the positional relation between the current stroke and the prior stroke are judged by combining traversing comparison conducted between the current stroke and the prior stroke with comparison conducted between the current stroke and the corresponding Chinese character stroke type code in the standard Chinese character stroke type code library, so that whether a stroke needs to be added is judged, and the point sets of the two strokes in the addition relation are combined to enable a complete stroke to be obtained. By the adoption of the stroke addition recognition method for the online handwritten Chinese characters, the stroke addition behavior which possibly exists when the user handwrites the Chinese characters in the online mode can be recognized, and the method has great significance in evaluating Chinese character writing quality, guiding Chinese character writing and recognizing the Chinese characters.

Description

technical field [0001] The invention relates to the technical field of evaluating Chinese character writing by using a computer, in particular to a recognition method for online handwritten Chinese character strokes on a handwriting platform. Background technique [0002] With the popularity of smart phones and tablet computers such as Android, handwriting technology based on touch screens has become more mature and widely used. When writing Chinese characters, due to many unavoidable reasons, it is often impossible to achieve the desired writing effect. Because the writer is not satisfied with a certain stroke that he has written, he often needs to modify this stroke. The act of the writer to continue writing a certain stroke of a certain Chinese character is a modification process of writing a correct and beautiful Chinese character, which reflects the writer's new understanding of the written Chinese character, which is acceptable in the teaching of conventional Chinese c...
