Review Questions
How do elastic body splines improve the process of shape registration compared to traditional methods?
Elastic body splines enhance shape registration by allowing for more flexible and natural deformations of shapes. Unlike traditional rigid transformations that may not account for variations in shape, elastic body splines enable smooth adjustments that align shapes while maintaining their intrinsic properties. This results in a more accurate correspondence between shapes, making it particularly valuable in fields like medical imaging where precision is crucial.
