SpectraFlow: Unifying Structural Pretraining and Frequency Adaptation for Medical Image Segmentation

Guowei Zou, Haitao Wang, Hejun Wu, Zhiquan Chen

Aligning images and binary masks in a shared latent space through latent transport regression produces transferable structural representations that improve medical image segmentation accuracy and boundary precision in low-data regimes.

Claims

C1strongest claim

Experiments on ISIC-2016, Kvasir-SEG, and GlaS demonstrate consistent gains over state-of-the-art methods, with improved robustness in low-data settings and sharper boundary delineation.

C2weakest assumption

That aligning images and binary masks through latent transport regression in a shared latent space produces task-agnostic structural representations that transfer effectively to downstream segmentation without bias from the mask generation or pretraining process.

C3one line summary

SpectraFlow combines structure-aware pretraining with mask-guided latent alignment and frequency-directional decoding to improve medical image segmentation accuracy and boundary sharpness in low-data regimes.
