Area of Science:

Computational biology
Image analysis
Microscopy

Background:

Cell instance segmentation in Electron Microscopy (EM) images is challenging due to numerous, densely packed cells with variable appearances.
Existing methods (pixel-wise classification, detection-segmentation) struggle with over-segmentation and under-segmentation, leading to inaccurate cell boundary detection.

Approach:

Proposes a novel approach using non-local correlation in the embedding space to enhance pixel feature distinctiveness.
This method aims to improve the separation of adjacent cell instances and the integrity of individual cell segmentation.

Key Points:

Non-local correlation helps make pixel features distinct or similar to neighbors, addressing segmentation errors.
Experiments on five EM datasets demonstrate superior performance compared to strong baselines.
The method significantly reduces false separations within cells and false fusions between cells.

Conclusions:

The proposed non-local correlation approach effectively improves cell instance segmentation accuracy in EM images.
This method offers a promising solution for analyzing complex cellular structures in biological imaging.
