Abstract
Procedures are described for blending images in real-time that avoid ghosting artifacts (attributable to moving objects), maintain the proper appearance of contiguous edges in the final image, and permits the use of fast (real-time) blending operations. A “guard-band” may be defined around an initially identified seam that perturbs the path of the initial seam so that both the seam and the guard-band's edges avoid moving objects by at least a specified amount. Rapid blend operations may then be performed in the region demarcated by the guard-band. The seam may be further adjusted to bias its position toward a specified trajectory within the overlap region when there is no moving object present. If visual registration techniques are not able to provide a properly aligned overlap region, motion sensor data for the image capture device, may be used instead to facilitate blending operations.
