Embodiment Construction

[0020] In order to better understand the present invention, the establishment process and evaluation system of the random stroke order database of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0021] (1) First, the writer uses the pressure-type handwriting board and the acquisition module to write the prescribed test character samples to establish a standard sample library.

[0022] The object of online handwritten Chinese character recognition, that is, the input of the recognition system, is the handwritten Chinese character expressed as a series of coordinate points. These coordinate points are obtained by sampling the trajectory of the pen tip during writing in the time domain. These data that record all the coordinate points of a single Chinese character are called POT data blocks, that is, handwriting data of online handwritten Chinese characters. Specifically, each POT data block contains...

Abstract

The invention relates to a method to build up random stoke order database and a evaluate system of online hand writing character recognition technology. The invention comprises the collection of standard sample database and the creation of random stoke order database. The evaluating system comprises: storage device used to store standard sample database and random order stoke database; collection module used to collect standard sample database; conversion module used to converse the online character stoke data into a two-value image; separating module used to separate at least one section form the two-value image according to the connection of the stoke; a creation module that includes a unit to disturb the stokes of every section and a unit to disturb the order of the sections.

Description

technical field [0001] The invention relates to an evaluation method of a handwritten Chinese character recognition system, in particular to a method for establishing a random stroke sequence library and an evaluation system for an online handwritten Chinese character recognition technology. Background technique [0002] In the field of handwriting recognition research, the construction of database becomes particularly important, which is an inevitable requirement for developing, evaluating and comparing different character recognition technologies. In view of the fact that the application range of online handwritten Chinese character recognition is getting wider and wider, and more and more institutions are participating in the research and development and promotion of online handwriting recognition technology, the General Administration of Quality Supervision, Inspection and Quarantine issued the national standard "Online Handwritten Chinese Character Recognition Technical ...
