Background:

Single-pixel imaging (SPI) decomposes imaging into modulation and reconstruction.
Deep learning frameworks improve SPI reconstruction but can lack physical constraints.

Purpose of the Study:

To propose a novel framework, equivariant plug-and-play-based single-pixel imaging (EPnP-SPI).
To enhance SPI reconstruction by incorporating physical constraints through transformation consistency.

Main Methods:

Incorporating equivariant imaging theory into a plug-and-play framework.
Enforcing equivariance on a denoiser to introduce transformation consistency.
Constraining deep neural network iterations using physical properties inherent to SPI.

Main Results:

EPnP-SPI demonstrated superior performance in simulations and optical experiments.
The method showed significant advantages at low sampling rates.
Transformation consistency provided additional physical constraints for network iterations.

Conclusions:

EPnP-SPI effectively integrates physical constraints into deep learning for SPI.
The proposed method enhances feature learning beyond data pairs.
EPnP-SPI offers improved image reconstruction for single-pixel imaging systems, particularly under data-scarce conditions.
