Abstract :
To satisfy the topology preservation requirement in deformable image registration, this research adopts a topological feature, the sign of the polygon area, as a regularization constraint. The reasonability and effectiveness of the proposed model are validated using synthetic image registration and inter-subject brain MRI image registration experiments.
