Patent Images
1. A method for decoding captured image information comprising:
- capturing image information, the image information including a predefined grid orientation comprising a plurality of pixels representing a plurality of corners;
determining a corner of the plurality of corners that is missing from the captured image information;
determining an angle to rotate the image information for decoding based upon the determined missing corner;
rotating the image information by the determined angle;
decoding said rotated image information;
error correcting said rotated image information; and
determining locations associated with said captured image information.

Abstract
A system and process for determining the location of a captured image from a larger image is described. A non-repeating sequence may be folded into a non-repeating array in which the array is unique for every sub window of a given size. The image of the sub window may be captured and its location determined within the non-repeating array.
