First Claim
Patent Images
1. A document processing system, comprising:
- one or more computer software programs stored on a computer readable medium comprising machine readable instructions for running an algorithm for the automatically removal the text from the signature area of a document;
wherein the document processing system provides a method for processing a document involving the automatic removal of text from a predetermined area of the document, the method comprising the steps of;
inputting a bitmap containing the predetermined area of the document from which the text will be removed, wherein the predetermined area contains handwritten strokes;
detecting the text;
removing the text and any handwritten strokes that intersect with the text; and
outputting the bitmap with the text removed therefrom.

20. A document processing system, comprising:
-
one or more computer software programs stored on a computer readable medium comprising machine readable instructions for running an algorithm for the automatically removal the text from the signature area of a document; wherein the document processing system provides a method for processing a document, comprising the steps of; inputting a bitmap containing a predetermined area of the document, wherein the predetermined area contains handwritten strokes and text; calculating a dominant letter height of the text;
computing text baselines and slope of the text;computing left and right boundaries of the text;
re-computing local baselines of the text;detecting intersections of handwritten strokes and text;
removing rough text from the re-computed local baselines;restoring any handwritten strokes that were previously removed from the predetermined area of the document; and outputting the bitmap with the text removed therefrom.
