Gleichzeitige Ausrichtung mehrerer Bildfragmente

摘要

Apparatus for aligning more than two fragments of an image to assemble the image provides high alignment quality between each pair of overlapping image fragments. Image registration operations are performed rapidly. The apparatus finds application in, for example, scanning, copying, and facsimile transmission of large format documents. A refined alignment is developed for each pair of overlapping fragments the refined alignment is only applied if the total alignment error for all fragments is improved. This is repeated to optimize the total alignment error.
