SpectralMamba-UNet: Frequency-Disentangled State Space Modeling for Texture-Structure Consistent Medical Image Segmentation

The paper proposes SpectralMamba-UNet, a frequency-disentangled framework that leverages discrete cosine transform to decouple and model low-frequency structural contexts and high-frequency boundary details via specialized state space mechanisms, achieving superior performance in medical image segmentation across diverse modalities.

From Calibration to Refinement: Seeking Certainty via Probabilistic Evidence Propagation for Noisy-Label Person Re-Identification

The paper proposes CARE, a two-stage framework that addresses noisy-label person Re-Identification by first dismantling softmax overconfidence through probabilistic evidence calibration and then refining sample selection via a composite angular margin and certainty-oriented sphere weighting to effectively distinguish clean hard positives from mislabeled data.

Plug-and-Play Diffusion Meets ADMM: Dual-Variable Coupling for Robust Medical Image Reconstruction

This paper proposes Dual-Coupled PnP Diffusion with Spectral Homogenization, a novel framework that restores dual variables to eliminate steady-state bias in medical image reconstruction while transforming structured residuals into statistically compliant noise, thereby resolving the bias-hallucination trade-off and achieving state-of-the-art fidelity with accelerated convergence.
