Abstract

Systems and methods are provided for handwriting recognition. Handwriting data is received. Geometric data of text in handwriting data is determined. Sub-characters of the text are determined. Sub-characters of text are matched to a model. Most probable characters of the text are determined based on the matching.

Claims (10)

1. A method for recognizing handwriting, the method comprising:

receiving handwriting data;

determining geometric data of text in handwriting data;

determining sub-characters of the text;

matching sub-characters of text to a model; and

determining most probable characters of the text based on said matching,

wherein the matching sub-characters of text to a model comprises:

estimating empirical conditional probability P(dlh) of parameter data based on hypothesis from order statistics of a parameter;

using signed functional distance that is not scalar; and

estimating non-parameterized empirical probability over stratified character and sub-character populations.
