Method and device for recognition of a handwritten pattern
First Claim
1. A method for recognition of a handwritten pattern, comprising:
- forming a representation of the handwritten pattern,forming at least two subconfigurations by dividing the representation of the handwritten pattern,processing the subconfigurations, said processing comprising;
comparing each subconfiguration with reference configurations,selecting at least one subconfiguration candidate for each subconfiguration among the reference configurations based on said comparing of each subconfiguration, anddetermining at least one candidate pattern consisting of one selected subconfiguration candidate for each subconfiguration,comparing the representation of the handwritten pattern to the candidate pattern, andcomputing a cost function based on the comparing of the representation of the handwritten pattern to the candidate pattern and on the comparing of the subconfigurations to the selected subconfiguration candidates in the candidate pattern in order to find a closest matching candidate pattern.

Abstract
A method for recognition of a handwritten pattern comprises the steps of forming (4) a representation of the handwritten pattern, forming (6) at least two subconfigurations by dividing the representation of the handwritten pattern, and processing the subconfigurations. The step of processing comprises the steps of comparing (8) each subconfiguration with reference configurations, selecting (10) at least one subconfiguration candidate for each subconfiguration among the reference configurations based on said step of comparing, and determining (12) at least one candidate pattern consisting of one selected subconfiguration candidate for each subconfiguration. The method further comprises the steps of comparing (14) the representation of the handwritten pattern to the candidate pattern, and computing (16) a cost function in order to find a closest matching candidate pattern. The cost function is based on the comparing of the representation of the handwritten pattern to the candidate pattern and on the comparing of the subconfigurations to the selected subconfiguration candidates in the candidate pattern.
