AI Technical Summary

Benefits of technology

This technology allows computers to recognise how they write onto paper documents without having them look like different types that people have already done beforehand. It also makes writing easier because there're no duplication required after each copying process. Overall, this technology simplifies document processing while improving efficiency and usability across multiple industries such as printing presses, manufacturing processes, advertisement placement, media distribution, and consumer electronics devices (CE).

Problems solved by technology

This patented technology solves two technical issues related to current systems used for recognizing and typing freehanded documents or writing script commands onto specialized devices like pens that require high cost equipment. Additionally, these solutions only work well if there're no other means available (such as an electronic pen) which makes it difficult for users who want more flexibility than traditional methods.

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.
