Phase-Aligned Finite-Fourier Periodic Deformation for 4D Medical Image Interpolation
A phase-aligned temporal reparameterization that maps normalized within-interval time to a latent motion phase according to deformation variation intensity, thereby better modeling non-uniform motion progression and achieving state-of-the-art performance over existing baselines.
