Problems solved by technology

However, handwriting tablets and tablet computers also have great disadvantages: they are expensive and unaffordable for ordinary people; when using them, they need to be carried with them
In addition, for handwritten fonts, such as handwritten manuscripts written on paper, and handwritten fonts and type materials printed on carriers, at present, computers cannot automatically recognize and input automatically, and need to rely on manual identification and input.

Embodiment Construction

[0031] The present invention will be further described below in conjunction with the embodiments and accompanying drawings.

[0032] 1. Process

[0033] include:

[0034] 1) the step of carrying out image preprocessing to the handwritten font that scanner inputs;

[0035] Such as figure 1 shown, also includes:

[0036] 2) the extraction of handwritten font glyph, its step comprises: line segmentation and word segmentation,

[0037] Line segmentation, using the horizontal projection of the text line for segmentation,

[0038] Word segmentation, using the vertical projection of text words for segmentation;

[0039] 3) modeling of computer fonts, the steps of which include: font feature vector extraction and classification;

[0040] 4) The modeling of handwritten fonts is the same as the modeling steps of computer fonts;

[0041] 5) text matching, its step comprises: the glyph feature vector extraction of computer and matching,

[0042] The glyph feature vector extraction...

Abstract

The hand writing distinguishing and inputting method in computer includes the following steps: image pre-treatment of the hand writing input from scanner; hand writing font extraction including line separation with the horizontal projection of text line and character separation with the vertical projection of text character; establishing template of computer font and hand written font including font characteristic vector extraction and classification; character matching including font characteristic extraction and matching in computer; and hand writing distinction via establishing the corresponding relation between hand writing font and computer font. The present invention is simple and convenient, and can facilitate man-machine conversation.

Description

technical field [0001] The invention relates to the technical field of Chinese information processing, in particular to a method for computer recognition and automatic input of handwritten characters. Background technique [0002] The computer recognition and automatic input system of handwritten characters is a very hot issue in the field of natural language processing. Its main function is reflected in the ability to process arbitrary handwritten manuscripts. The popular handwriting tablet on the market and the tablet computer launched by Microsoft have solved the time-consuming problem of text entry to a certain extent, reflecting the superiority of office automation. However, handwriting tablets and tablet computers also have great disadvantages: they are expensive and unaffordable for ordinary people; they need to be carried with them when using them. In addition, for handwritten fonts, such as handwritten manuscripts written on paper, and written materials such as han...
