Outline

This paper proposes HazeMatching, a computational dehazing technique, to address the problem of blurry image data from inexpensive and accessible wide-field microscopes. HazeMatching uses an iterative approach, modifying the conditional flow matching framework to incorporate blurry observations into the conditional velocity field, aiming to balance data accuracy (MSE, PSNR) and perceptual realism (LPIPS, FID). We evaluate our method against seven existing methods on five datasets, including synthetic and real data, and demonstrate that it effectively balances accuracy and realism while generating well-calibrated predictions. Its applicability to real-world microscopy data without the need for explicit degradation operators is a key advantage, and the data and code used will be made publicly available.

Takeaways, Limitations

Takeaways:
It presents new possibilities for obtaining high-quality microscopic images with an affordable wide-field microscope.
We present a novel dehazing method that effectively balances data accuracy and perceptual realism.
It is highly versatile as it can be applied to real data without explicit degradation operators.
Reproducibility and scalability are achieved through open data and code.
Limitations:
Further research is needed to determine how well the proposed method's performance generalizes across different microscope setups and data types.
Detailed descriptions of optimization or parameter tuning processes for specific microscope setups may be lacking.
Additional validation may be required for robustness to various noise types or artifacts.
