Embodiment Construction

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

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

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

[0037] Record the traces left by the strokes of handwritten Chinese characters from the beginning to the end. According to the cosine value of the angle between the straight line and the horizontal line formed by two adjacent points on the track, the plane coordinate system is divided into up, down, left, right, There are eight directions in the upper left, lower left, upper right, and lower right. Eight Arabic numerals or other means are used to represent the eight directions. The direction code is used to indicate the type of strokes. For complex strokes, it is divided into several independent strokes. The trend code is co...

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 the writing of Chinese characters by using a computer, in particular to a method for recognizing the stroke renewal of online handwritten Chinese characters on a handwriting platform. Background technique [0002] With the popularization of Android and other smart phones and tablet computers, handwriting technology based on touch screens has become more mature and widely used. When writing Chinese characters, due to many unavoidable reasons, the ideal writing effect is often not achieved. Because the writer is not satisfied with a stroke he has written, he often needs to continue to modify the stroke. The behavior of the writer to renew a certain stroke of a Chinese character is the process of writing a correct and beautiful Chinese character. It reflects the writer’s re-recognition of the written Chinese character. This is acceptable in conventional Chinese character writing teaching However, thei...
