Digital image stitching
First Claim
Patent Images
1. A method comprising:
- identifying first overlap information regarding where at least two digital images overlap at a first resolution level;
purging memory, subsequent to said identifying, of the at least two digital images at the first resolution level;
retrieving, subsequent to said purging, overlapping areas of the at least two digital images at a second resolution level higher than the first resolution level based on the first overlap information; and
identifying second overlap information regarding where overlapping ones of the retrieved overlapping areas overlap at the second resolution level.

Abstract
Where at least two digital images overlap at a first resolution level is identified. Overlapping areas of the at least two digital images at a second resolution level higher than the first resolution level are obtained. Where the overlapping areas overlap at the second resolution level is identified.
