Embodiment Construction

[0089] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0090] One of the purposes of the hand-drawn shape recognition in the embodiment of the present invention is to convert the original input that cannot be recognized by the computer, including closed graphics with arbitrary shapes, into graphics that can be recognized by the computer. Based on the above purpose, one of the core concepts of the embodiments of the present invention is to collect hand-drawn shape feature templates, generate a feature template library, and establish the association between each hand-drawn shape feature template and a preset standard display shape; on this basis, identify the user The input of the hand-drawn shape in the original input is matched with the feature template library to obtain the feature te...

Abstract

The invention discloses a method for recognizing hand-painted shapes, comprising the steps of: collecting a hand-painted shape feature template to generate a shape feature template bank, and establishing correlation between the hand-painted shape feature template and the corresponding standard shape template; receiving stroke data to be recognized and input by a user, and extracting feature information of the hand-painted shape stroke data when the stroke data to be recognized comprises hand-painted shape stroke data in conformity with a preset rule; matching the feature information in the hand-painted shape feature template to obtain the hand-painted shape feature template with the highest matching degree; and extracting the standard shape template corresponding to the hand-painted shape feature template as the recognition result. The invention can simply and conveniently realize various hand-painted shapes input, in particular complex hand-painted shape input, thus ensuring the user to obtain better use experience.

Description

technical field [0001] The invention relates to the field of pattern recognition, in particular to a hand-drawn shape recognition method and a hand-drawn shape recognition device. Background technique [0002] Pattern recognition is a technology that uses computers to automatically recognize information in various forms (such as numerical forms, text forms, and logical relationship forms) that represent things or phenomena, such as pictures, text, symbols, and sounds. At present, handwriting recognition technology, as an aspect of pattern recognition, has been widely used. Handwriting recognition technology is based on the recognition of handwriting input strokes, and converts the information input by users through some input devices (such as mobile terminals, handwriting tablets, etc.) into a form that can be read by computers and can be directly processed. [0003] In the prior art, handwriting recognition technology is mainly used for character recognition, such as the a...
