Spatiotemporal imaging arises in many applications and the minisymposium aims to bring together leading experts and young researchers in the processing of such imaging data. The field is undergoing rapid development where a variety of mathematical methods (shape theory, regularization method, local analysis, algorithm) play a pivotal role in improving the reconstruction and analysis of spatiotemporal images, e.g. motion estimation in reconstruction (4D CBCT, pulmonary PET-CT, cardiac SPECT-CT, electron microscopy), predicting the evolution of a disease. The high diversity in mathematical techniques makes it very challenging for a single researcher to embrace the full spectrum of this rapidly evolving field.
