We propose a new image reconstruction model for spatiotemporal imaging in large deformation diffeomorphic metric mapping framework. This model can be divided into two sub-problems, where one is the usually static image reconstruction, and the other is the so-called indirect image registration. The indirect registration uses diffeomorphisms that transform the template to be reconstructed through a group action, which are generated by a flow equation that is defined by a velocity field with certain regularity.
