Abstract

Embodiments of the present disclosure may include methods, systems, and machine readable and executable instructions and/or logic. An example method for creating a handwritten character font library can include receiving a set of standard characters to a computing device, and deriving a group of character components from the initial set of characters. A subset of characters is selected from the set of standard characters, the subset collectively including substantially all the group of character components. Handwritten characters corresponding to the subset of characters are received to the computing device, and handwritten character components are extracted from the hand written characters corresponding to the group of character components. A set of handwritten characters is then constructed from the received handwritten characters and/or the handwritten character components.

Claims

1. A method for creating a handwritten character font library, comprising:

receiving a set of standard characters to a computing device;

deriving a group of character components from the initial set of characters;

selecting a subset of characters from the set of standard characters, wherein the subset collectively includes substantially all of the group of character components;

receiving, to the computing device, handwritten characters corresponding to the subset of characters;

extracting handwritten character components from the hand written characters corresponding to the group of character components; and

constructing a set of handwritten characters from the received handwritten characters and/or the handwritten character components.

2. The method of claim 1, wherein the character components are unique irrespective of size and/or location within a character, and are unconnected from one another.

3. The method of claim 1, further comprising generating a template of sample characters to indicate to a user the handwritten characters to be received.

4. The method of claim 1, wherein subset of characters only includes a minimum quantity of characters from the set of standard characters that collectively includes all the group of character components.

5. The method of claim 1, wherein a quantity of characters included in the subset of characters is approximately 20% or less of the characters included in the set of standard characters.

6. The method of claim 1, wherein there is a one-to-one correspondence between the characters of the set of handwritten characters and the characters of the set of standard characters.

7. The method of claim 1, wherein constructing a set of handwritten characters includes merging character components level by level to form a character component segmentation hierarchy according to predefined heuristic rules.

8. The method of claim 1, further comprising storing an organization hierarchy of all character components with their relative size and position associated with each character of the set of standard characters.

9. The method of claim 1, further comprising grouping visually similar character components into clusters, such that character components in a same cluster can be replaced by each other through a series of similarity transformations when constructing a particular character.

10. The method of claim 1, further comprising storing the position of separators between dividable character components associated with a particular character.

11. The method of claim 1, wherein the set of standard characters are Chinese characters.

12. The method of claim 11, wherein the set of standard characters is the GB2312 character set.

13. The method of claim 1, wherein the set of standard characters is based on the simplified Chinese KaiTi font character set.

14. A non-transitory computer-readable medium having computer-readable instructions stored thereon that, if executed by one or more processors, cause the one or more processors to:

receive a set of standard characters to a computing device;

derive a group of character components from the initial set of characters;

select a subset of characters from the set of standard characters, wherein the subset collectively includes substantially all of the group of character components;

receive, to the computing device, handwritten characters corresponding to the subset of characters;

extract handwritten character components from the hand written characters corresponding to the group of character components; and

construct a set of handwritten characters from the received handwritten characters and/or the handwritten character components.

15. A computing system, comprising:

a computing device having at least one processor;

a production device communicatively coupled to the computing device; and

a non-transitory computer-readable medium having computer-readable instructions stored thereon that, if executed by the at least one processor, cause the at least one processor to;

receive a set of standard characters to a computing device;

derive a group of character components from the initial set of characters;

select a subset of characters from the set of standard characters, wherein the subset collectively includes substantially all of the group of character components;

receive, to the computing device, handwritten characters corresponding to the subset of characters;

extract handwritten character components from the hand written characters corresponding to the group of character components; and

construct a set of handwritten characters from the received handwritten characters and/or the handwritten character components.
