JPH0567241A - Online handwritten character recognition device - Google Patents

Abstract

PURPOSE:To move new pattern data for collation, which is obtained by means of learning and which has a writing habit, between devices so as to improve recognition processing efficiency in an online handwritten character device. CONSTITUTION:A character recognition pattern extraction part 2 extracts recognition patter information 102 from handwritten character information 101 inputted from a handwriting tablet 1, and it is held in a pattern holding buffer 3. A collation operation part 4 outputs similarity between reference pattern data 103 for collation in a pattern base part 5 and recognition pattern information 102, and a character decision part 8 decides a decision character 106 based on the size. New pattern data 105 for collation obtained by learning for recognizing the individual writing habit among standard collation data in the pattern data base 5 is held in a portable card storage medium 9 so as to move it.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an on-line handwritten character recognition device.

[0002]

2. Description of the Related Art Conventionally, in this type of online handwritten character recognition device, a character recognition pattern, which is a reference for recognition and verification, is registered in the device, and a character that cannot be recognized due to personal writing is It was learned by learning and additionally registered as a new character recognition pattern in the character recognition pattern in the device.

[0003]

In the above-described conventional online handwritten character recognition device, in order to recognize a character that is personally written by the user, a new character recognition pattern for collation learned by learning. Has no means for registering in the other on-line handwritten character recognition device, which has a drawback that effective use of the new character recognition pattern data is limited.

An object of the present invention is to eliminate the above-mentioned drawbacks and to enable a new character recognition pattern newly registered by learning to be registered in another on-line handwritten character recognition device, thereby effectively utilizing the new character recognition pattern data. It is to provide an online handwritten character recognition device which is expanded.

[0005]

The on-line handwritten character recognition device of the present invention stores a personally written character obtained by learning as a new character recognition pattern for collation in a portable card-shaped storage medium, It is portable and can be newly registered for each device.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention.

The embodiment shown in FIG. 1 is a handwriting tablet 1.
A character recognition pattern extraction unit 2 for extracting a character recognition pattern from a handwritten character, a pattern holding buffer 3 for temporarily storing the extracted recognition pattern, a matching calculation unit 4 for matching the similarity with a standard pattern, and a similarity. A pattern database 5 that stores standard patterns for collation, a character determination unit 8 that determines characters based on the degree of similarity obtained by collation, and a portable card shape that stores recognition patterns for each person who has a dictation. The storage medium 9 and a personal pattern input interface 10 serving as an interface for registering the recognition pattern of the portable card-shaped storage medium 9 in the pattern database 5 are provided.

The pattern database 5 is provided with a standard pattern database 6 for storing previously registered recognition patterns and a personal pattern database 7 for registering the stored contents of the portable card-shaped storage medium 9.

Next, the operation of this embodiment will be described.

From the handwritten character information 101 input from the handwriting tablet 1, the recognition pattern information 102 is extracted by the character recognition pattern extraction unit 2, and the pattern holding buffer 3 is then extracted.
Temporarily held in.

In the matching calculation unit 4, the recognition pattern information 102
And the standard pattern database 6 of the pattern database 5
Is compared with the reference pattern data 103 for matching registered in the, and the similarity parameter 1 indicating the similarity between the two.
04 is calculated and output.

The character determination unit 8 determines the highest similarity determined by collation as a standard pattern that matches the input character, and determines the corresponding character of this standard pattern as the determination character 10.
Output as 6.

The pattern database 5 has a standard pattern database 6 and a personal pattern database 7 used for character recognition with a writing style for each individual who uses the apparatus. The individual pattern database 7 has a writing style. The new verification pattern data is registered as a standard pattern.

The standard patterns registered in the personal pattern database 7 are intended for users who have ill-written characters that cannot be collated in the standard pattern database 6, and their handwritten characters can be obtained by learning. This learning is performed using a known learning method by either diverting the present device or using a dedicated learning system.

The new collation pattern data registered in the personal pattern database 7 is stored in the portable card-shaped storage medium 9 and held for each user, and loaded into the personal pattern database 7 through the personal pattern input interface 10. ..

In this way, the personal pattern of a user who has a writing mistake can be movably registered and used for character recognition without learning each time between devices.

[0018]

As described above, according to the present invention, of the standard pattern data used as a reference for collation, the new pattern data obtained by learning for recognizing the characters of an individual who has a writing stroke is stored in a portable card-like memory. Separation as a medium makes it possible to move to another on-line handwritten character recognition device, has the effect of reducing the time and effort required to newly learn the personal writing style for each device used, and significantly increasing the recognition efficiency.
