Background:

3D volume imaging is crucial for understanding neuronal organization and function.
Accurate foreground estimation is vital for neuronal image quantification (soma counting, neurite tracing, reconstruction).
Variations in imaging and labeling create complex neuronal images, challenging existing estimation methods.

Purpose of the Study:

To propose a robust sparse-smooth model (RSSM) for effective foreground and background separation in neuronal images.
To enhance the accuracy and robustness of foreground estimation across diverse neuronal imaging datasets.

Main Methods:

Developed a novel robust sparse-smooth model (RSSM).
Incorporated distinct smoothness levels for foreground and background.
Utilized the sparsity of the foreground as a prior constraint.

Main Results:

The RSSM method demonstrated robust foreground estimation across various neuronal images.
It improved the performance of existing neurite tracing and soma locating tools.
Quantified results were comparable or superior to those from original images.

Conclusions:

The RSSM method offers a robust solution for foreground estimation in complex neuronal images.
It enhances the usability of current quantitative analysis tools for neuroscience research.
This approach facilitates more accurate and reliable analysis of neuronal structures.
