Background:

Accurate neuron segmentation in electron microscopy (EM) is crucial for understanding neural circuits.
Existing automated methods often require significant manual correction, impacting efficiency.

Purpose of the Study:

To present a novel graphical-model-based method for automatic and interactive neuron segmentation in EM images.
To improve the efficiency and accuracy of neuron reconstruction pipelines.

Main Methods:

A learning-based model using a conditional random field (CRF) on a hierarchical merging tree (watershed merging tree).
Maximum a posteriori (MAP) prediction for automated segmentation.
An interactive framework utilizing model uncertainty (marginals) for efficient user proofreading and global segmentation improvement.

Main Results:

Achieved segmentation quality comparable to state-of-the-art methods.
Demonstrated efficient inference and training due to the tree-structured graph.
Developed an interactive system that significantly enhances segmentation accuracy through targeted user feedback.

Conclusions:

The proposed method offers an efficient and accurate approach to neuron segmentation in EM data.
The interactive component effectively addresses the need for high segmentation quality by leveraging user corrections.
This combined automated and interactive strategy optimizes the neuron reconstruction pipeline.
