Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings. The invention evaluates the writing quality of handwritten Chinese characters in terms of strokes, components and whole characters. The overall process is attached figure 1 shown.

[0015] For the convenience of description, the following settings are made (all indicators are applicable):

[0016] Subscript T: indicates a template; subscript U: indicates user's handwriting; S: indicates a certain stroke, pt: indicates a certain point in the stroke; Comp: indicates a certain component.

[0017] The specific content of each step is described below:

[0018] 1. Pretreatment

[0019] This step mainly restores and processes the template and the timing information written by the user, so as to facilitate the subsequent steps. Including template loading, user writing stroke inspection, normalization, trajectory sampling and reconstruction 5 parts, the flow chart is attache...

Abstract

The invention provides a handwritten Chinese character layout evaluation method. The method comprises the following steps: (1), pretreatment; (2), performing evaluation to the position layout of each stroke in a handwritten Chinese character; (3), performing layout evaluation to all the parts in the handwritten Chinese character by part layout evaluation; (4), performing evaluation to the integral form of the handwritten Chinese character by integral font evaluation; and (5), combining the results of evaluation in the steps (2), (3) and (4) to obtain the evaluation conclusion. The invention adopts the five steps of pretreatment, stroke layout evaluation, part layout evaluation, integral form evaluation and overall evaluation, and obtains the evaluation conclusion by measuring nine kinds of indexes, the conclusion takes the character reasoning as a primary way and the grading as an auxiliary way, and the writing quality of the users is effectively classified by grade according to the index value.

Description

technical field [0001] The invention belongs to the field of pattern analysis and pen calculation, in particular to a handwritten Chinese character layout evaluation method. technical background [0002] Pen-based interaction mainly uses the two media of handwritten text and hand-drawn sketches as the main way of human-computer interaction, and the recognition technology of handwritten text and hand-drawn sketches is the core of pen-based interaction technology. Handwritten characters are an important research object of pen-based interaction. Different from handwritten Chinese characters, the quality evaluation of handwritten Chinese characters is to use computers to automatically identify the writing quality of users' handwritten Chinese characters, including whether the writing is correct and neat. It belongs to the category of pattern recognition and artificial intelligence in disciplines; it belongs to computer-assisted teaching in application. Chinese character writing...
