Query: Vertebrae segmentation, identification and localization using a graph
  optimization and a synergistic cycle   This paper considers the segmentation, identification and localization of
vertebrae in CT images. Although these three tasks are related, they face
specific problems that add up when they are addressed together. For example
neighboring vertebrae with similar shapes perturb the identification and
vertebrae with complex or even pathological morphologies impact the
segmentation. Consequently, the three tasks tend to be approached
independently, e.g. labelling (localization and identification) or segmenting
only, or, when treated globally, a sequential strategy is used. Sequential
methods however are prone to accumulate errors as they are not able to recover
from mistakes of the previous module. In this work, we propose to combine all
three tasks and leverage their interdependence: locations ease the
segmentation, the segmentations in turn improve the locations and they all
contribute and benefit from the identification task. To this purpose we propose
a virtuous cycle to enforce coherence between the three tasks. Within such a
cycle, the tasks interoperate and are iterated until a global consistency
criterion is satisfied. Our experiments validate this strategy with
anatomically coherent results that outperform the state of the art on the
VerSe20 challenge benchmark. Our code and model are openly available for
research purposes at https://gitlab.inria.fr/spine/vertebrae_segmentation.
