The throughput of electron microscopes has increased significantly in recent years,
enabling detailed analysis of cell morphology and ultrastructure in fairly large tissue volumes. Analysis of neural circuits at single-synapse resolution remains the flagship target of this technique, but applications to cell and developmental biology are also starting to emerge at scale. On the light microscopy side, continuous development of light-sheet microscopes has led to a rapid increase in imaged volume dimensions, making Terabyte-scale acquisitions routine in the field.
The amount of data acquired in such studies makes manual instance segmentation, a fundamental
step in many analysis pipelines, impossible.
While automatic segmentation approaches have improved significantly thanks to the
adoption of convolutional neural networks, their accuracy still lags behind human annotations
and requires additional manual proof-reading.
A major hindrance to further improvements is the limited field of view of the segmentation networks
preventing them from learning to exploit the expected cell morphology or other prior biological knowledge which
humans use to inform their segmentation decisions.
In this contribution, we show how such domain-specific information can be leveraged by expressing it as long-range interactions
in a graph partitioning problem known as the lifted multicut problem.
Using this formulation, we demonstrate significant improvement in segmentation accuracy for four challenging boundary-based
segmentation problems from neuroscience and developmental biology.
