10 February 2009 Ensemble registration: aligning many multi-sensor images simultaneously
Author Affiliations +
To register three or more images together, current approaches involve registering them two at a time. This pairwise approach can lead to registration inconsistencies. It can also result in diminished accuracy because only a fraction of the total data is being used at any given time. We propose a registration method that simultaneously registers the entire ensemble of images. This ensemble registration of multi-sensor datasets is done using clustering in the joint intensity space. Experiments demonstrate that the ensemble registration method overcomes serious issues that hinder pairwise multi-sensor registration methods.
