• To improve the scattering reconstruction capability of SIM for biological tissues.
• To overcome resolution limitations in SIM imaging caused by scattering.

Main Methods:

• Developed a multi-frame wavelet generation adversarial network (MWGAN).
• Utilized wavelet transform within a generative adversarial network to reconstruct cellular structure details.
• Employed a multi-frame adversarial network to leverage inter-frame image information for improved reconstruction quality.

Main Results:

• MWGAN demonstrated robust performance on multiple low-quality SIM image datasets.
• The proposed method outperformed state-of-the-art techniques in both subjective and objective evaluations.
• MWGAN effectively improved the clarity and reconstruction quality of complex cellular regions in SIM images.

Conclusions:

• MWGAN significantly enhances the clarity of SIM images, particularly in scattering biological tissues.
• Multi-frame reconstruction improves the quality of complex cellular structures.
• The method facilitates clearer, dynamic observation of cellular functions, advancing life science research.
