Abstract :
This paper describes and compares image registration techniques for situations in which one or both candidate images are partially occluded. Both fractional masks (introduced) and binary masks improve registration accuracy. Efficient mask-based algorithms operate at low resolution on low-pass subbands of wavelets and correlate images in the frequency domain
