Description

Computer handwriting Chinese character set creation and application system

The invention relates to a computer handwriting set creation and application system, in particular to a computer handwriting Chinese character set creation and application system suitable for use in a smart terminal.

Although the computer system provides a variety of text fonts or glyphs for users to display and print various documents, the glyphs provided by the computer are difficult to surpass the charm of handwriting. Many people still want to read handwritten letters or documents or write handwritten letters or documents. The variability and uniqueness of handwriting are indeed not replaced by standard computer glyphs.

Making documents by hand is slow and time-consuming, and often cannot meet the speed requirements of modern people. Today's computer equipment does not yet provide convenient tools for entering document content by hand. For example, a tablet that is sufficient for the resolution of handwritten text is expensive. It is time-consuming to enter handwritten documents by scanning, and the imported documents cannot be edited. Various tools have been developed to provide handwriting input of computer glyphs.

United States Patent Publication US 20060078203 A1, the invention name Realistic machine-generated handwriting with personalized fonts provides a technology for generating handwriting shapes by computer to create computer handwriting sets. According to the invention, the variation parameters of the handwriting shape include classification parameters, such as handwriting characteristics based on age, region, race, and gender; personal characteristics, such as handwriting characteristics generated by personal writing habits; and random Parameters, such as handwriting characteristics due to factors such as writing pressure, font size, slope, stroke style, etc. The invention extracts the above-mentioned characteristic parameters according to most characters written by an individual, and then processes the glyphs of the printed font according to the obtained parameters, so that the glyphs are changed into glyphs with a handwriting style, which is called "realistic" handwriting . The glyphs produced by this invention are not actually handwriting, but are the result of modifying standard computer glyphs. And because of the simple classification, it can only be applied to Pinyin text with only a few letters, such as English.

United States Patent Publication US 20130181995 A1, the invention name Handwritten character font library provides a handwriting character set creation technology. The invention extracts the radicals of Chinese characters from the characters in the training Chinese handwritten file and combines them into a new handwriting shape. According to the patent, a character set with 2,500 Chinese characters is enough to cover 97.97% of the commonly used Chinese characters. And all of these 2,500 words can be generated from the 522 Chinese characters in the above-mentioned way. Therefore, as long as the user writes these 522 Chinese characters, the computer can automatically generate a character set containing 2,500 Chinese handwriting characters.

United States Patent Publication US 20140344684 A1, the invention name System for generating unique handwriting style of user and method therefor provides a Korean handwritten pinyin glyph combination method. According to the invention, as long as the user inputs 59 handwritten Korean letters (phonemes of Hangul), the system of the invention can generate all the Korean handwritten text through deformation, combination, and the like.

WIPO patent application WO 2016209495 A1, Substitution of handwritten text with a custom handwritten font, proposes a handwritten text recognition system. In view of the conventional handwriting recognition technology, the shape of the scanned handwriting is compared with the standard glyph. The invention claims that the handwritten text to be recognized should be compared with the handwritten text written by the same person to improve the comparison. Correct rate. The invention also proposes a technique for constructing a handwritten character set.

Although the above-mentioned known technologies propose techniques for establishing a handwriting set, they are all aimed at establishing a complete handwriting set for the purpose or premise. Even if some proposals are to create a character set with a part of the text shape in the standard character set, such as the aforementioned US 20130181995 A1, the font file is still created (or recognized by the Chinese national standard) as a common character set. Although the invention claims that as long as 250-500 words are written, a custom word set can be established, in fact, it is still inadequate to use in professional documents or documents in specific fields, such as scientific and technological literature, professional papers, and legal documents.

US patent publication US 20140176564 A1, the invention name Chinese Character Constructing Method and Device, Character Constructing Method and Device, and Font Library Building Method proposes a method of using a character component in the character) parameter. The patent believes that through this method, "a large font library containing hundreds of thousands of characters" can be established, and the trouble of creating glyph data one by one by hand is eliminated.

Chinese patent CN 101377854 B1 is about a method for computer to imitate Chinese handwriting. This method is used to generate handwritten characters according to the simplified Chinese standard computer glyphs. The steps include: pre-dividing and classifying existing handwritten Chinese character samples, parameterizing each stroke, radical, whole character, and internal structure of the font written by each user, and establishing a personal handwritten font database. To imitate Chinese characters, do pen division and parameterization on their corresponding italics. Each radical or stroke of the Chinese character to be imitated is constructed one by one according to the personal handwritten font database. According to the personal handwriting font database, the internal space structure of the Chinese character to be imitated is simulated, and the radicals or strokes obtained by the imitation are stitched into a complete Chinese character as the result of the imitation handwriting.

It can be known from the observation of the prior art that there is indeed a considerable demand for Chinese handwriting sets in the industry. Industry players are also constantly working to develop tools that provide Chinese handwriting applications. However, the existing Chinese handwriting application technology focuses on developing a complete character set. Due to the large number of Chinese characters, in order to simplify the process of creating Chinese handwriting sets, the methods proposed by the industry include: providing only common character sets, grouping characters with characters such as radicals, and automatically generating handwriting shapes by computers. But all solutions still require the creator to enter a considerable amount of Chinese characters by hand. The proposed method is difficult to be widely accepted by the general public.
