By introducing directed infinite links connecting pixels at the same spatial locations in successive image frames, we impose shape growth/shrinkage constraint in graph cuts. Minimization of energy computed on the resulting graph of the image sequence yields globally optimal segmentation. We validate the proposed approach on two applications: segmentation of melting sea ice floes from a time series of multimodal satellite images and segmentation of a growing brain tumor from sequences of 3D multimodal medical scans. In the latter application, we impose an additional inter-sequences inclusion constraint by adding directed infinite links between pixels of dependent image structures. %G English %2 https://inria.hal.science/hal-00856634/document %2 https://inria.hal.science/hal-00856634/file/2013_BMVC_TarabalkaEtAl.pdf %L hal-00856634 %U https://inria.hal.science/hal-00856634 %~ INRIA %~ INRIA-SOPHIA %~ INRIASO %~ INRIA_TEST %~ ASCLEPIOS %~ TESTALAIN1 %~ INRIA2 %~ INRIA-ETATSUNIS
