Visualization appraising method for Chinese character handwriting irrespective of writing words content

Abstract

The invention discloses a visualized Chinese script authentication method independent of written literal content. The method comprises the following steps: 1) collecting and storing value and direction of the moving speed of a nib of a handwriting pen, and pressure of the nib on the handwriting pad in every T_step seconds while a user writes characters with the handwriting pen on a handwriting pad; 2) calculating distribution information of the value and the direction of the moving speed of the nib of the handwriting pen and the pressure of the nib on the handwriting pad after the user finishes the writing process, and visualizing the distribution information; 3) sorting all the collected data after the writing process is finished, and visualizing the information of each category; and 4) authenticating the trueness of the script according to the similarity of the visualization results. The visualized Chinese script authentication method independent of the written literal content is characterized by analyzing and visualizing writing habit of the user, and authenticating the script according to the visualization result, and can rapidly, stably and accurately authenticate the trueness of the script.

Description

technical field [0001] The invention relates to data analysis and visualization technology, in particular to a method for visual identification of handwriting of Chinese characters which has nothing to do with the contents of written characters. Background technique [0002] Visualization is the theory, method and technology of using computer graphics and image processing technology to convert data into graphics or images and display them on the screen for interactive processing. It involves many fields such as computer graphics, image processing, computer vision, and computer-aided design, and has become a comprehensive technology for studying a series of issues such as data representation, data processing, and decision analysis. Scientific computing visualization can turn scientific data, including measured values, images, or digital information involved in calculations into intuitive, graphical image information, physical phenomena or physical quantities that change with ...

AI Technical Summary

Problems solved by technology

[0003] So far, handwriting identification has been achieved by comparing the shape of handwriting, but the defect of this method is that the shape or handwriting style is easy to imitate, and even can be imitated by algorithms, and there are still writing problems when identifying calligraphy works of different users The content may change, which will greatly reduce the accuracy of handwriting identification. On the other hand, the user's writing habits are almost impossible to imitate, so shape comparison can be assisted to achieve more accurate handwriting identification
