CoordFormer: Give Me Any Coordinates and I Will Give You Labels

Semantic segmentation on very-high-resolution images remains challenging due to the high computational cost and the difficulty of capturing fine-grained details. We propose CoordFormer, a novel coordinate-based architecture for semantic segmentation that predicts labels at arbitrary spatial locations through a Coordina...

Spectral Gating via Damped Oscillations for Adaptive Implicit Neural Representations

This work proposes to model each neuron's activation as the steady-state response of a sinusoidally-forced damped harmonic oscillator, whose amplitude naturally governs the network's spectral selectivity during training, and achieves state-of-the-art or competitive results against established INRs, while requiring no t...
