Gauge-Equivariant Attention for Rotation-Stable $360^\circ$ Scene Understanding

Panoramic $360^\circ$ scene understanding increasingly relies on icosphere transformers, but a state-of-the-art spherical model loses more than half of its segmentation accuracy when the camera rotates by $90^\circ$, and controlled ablations identify gauge dependence in its relative-position bias as a major contributor...

Leap-mamba: locality-enhanced feature calibration with pixel-region dual-stream vision mamba UNet for medical image segmentation

A Pixel–Region VSSblock that comprises a local-Mamba branch and a global-Mamba branch to simultaneously capture fine-grained details and high-level semantic context and a Hierarchical Feature Calibration Module (HFCM) that leverages multi-scale context awareness and a structural saliency filtering mechanism to dynamica...
