Multi-resolution spatial feature extraction for automatic handwriting recognition
First Claim
1. A system of recognizing content, comprising:
- a processor configured to;
determine a first value representative of a pixel content present at a first set of pixels of a bitmap associated with a first distance from a pixel under consideration of the bitmap;
determine a second value representative of a pixel content present at a second set of pixels of the bitmap associated with a second distance from the pixel under consideration; and
use the first and second values to compute one or more spatial features associated with the pixel under consideration for purposes of content recognition; and
a memory coupled to the processor and configured to provide the processor with instructions.

Abstract
A first technique of recognizing content is disclosed, including: determining a first value representative of a pixel content present at a first set of pixels associated with a first distance from a pixel under consideration; determining a second value representative of a pixel content present at a second set of pixels associated with a second distance from the pixel under consideration; and using the first and second values to compute one or more spatial features associated with the pixel under consideration for purposes of content recognition. A second technique of recognizing content is also disclosed, including: determining, for a pixel, a first value representative of a first feature associated with a set of pixels associated with a first direction from the pixel; and determining, for the pixel, a second value representative of a second feature associated with a set of pixels associated with a second direction from the pixel.
