The paper introduces Complex-Valued Quadratic Phase Gaussian (CVQPG), a new hologram representation that replaces standard 2D Gaussian splatting with 2D quadratic phase functions. CVQPG adds learnable parameters to control the curvature of these bases, and the authors demonstrate that it improves visual quality by +0.19 dB (RGB) and +0.33 dB (grayscale) over state‑of‑the‑art methods while keeping the same parameter count. Frequency‑domain analysis shows that CVQPG preserves the mid‑to‑high frequency band of natural images.

4D Gaussian Splatting (4DGS) excels in dynamic 3D reconstruction and real-time novel view synthesis via efficient 4D Gaussian representations and parallelizable rendering. However, existing 4DGS approaches rely on a single polynomial to model motion, which limits performance in complex dynamic scenes where high-frequency motion components are prevalent, and fails to ensure long-term stability due to cumulative trajectory drift.
