Area of Science:

Computational imaging
Biomedical imaging
Machine learning for imaging

Background:

Sequential computational imaging is prone to motion artifacts in dynamic scenes.
Existing methods often require data priors or pre-training, limiting their applicability.
Motion artifacts can lead to misinterpretation of biological processes.

Purpose of the Study:

To develop a novel method for joint estimation of scene and motion dynamics in computational imaging.
To remove motion artifacts and resolve sample dynamics from raw measurements.
To enable accurate reconstruction and analysis of dynamic biological systems.

Main Methods:

A neural space-time model (NSTM) was proposed.
The NSTM jointly estimates scene and motion dynamics.
No data priors or pre-training were required.

Main Results:

NSTM effectively removes motion artifacts from reconstructed images.
The model successfully resolves sample dynamics.
Demonstrated performance across differential phase-contrast microscopy, 3D structured illumination microscopy, and rolling-shutter DiffuserCam.

Conclusions:

NSTM offers a unified approach to artifact removal and dynamic analysis in computational imaging.
The method accurately recovers subcellular motion dynamics.
Reduces misinterpretation of living systems caused by motion artifacts.
