We introduce Complex-Valued Quadratic Phase Gaussian (CVQPG), a novel hologram representation method that augments each 2D Gaussian primitive with a quadratic phase profile controlled by a learnable curvature parameter. Against the planar Gaussian baseline, CVQPG improves the average PSNR of holographic reconstructions by 0.19 dB (RGB) and 0.33 dB (grayscale) at equal primitive counts, and by 0.05 dB (RGB) and 0.08 dB (grayscale) at equal parameter counts, where it still leads in all visual quality metrics. Our frequency-domain analysis shows that CVQPG better preserves the mid-to-high frequency band of natural images, where the reconstruction MSE drops by up to 11% (RGB) and 22% (grayscale), indicating that modulating primitive wavefronts is an effective and lightweight enhancement.
Phase-only hologram (POH) generation remains a fundamental challenge in holographic displays because of the inherent difficulty in encoding complex amplitudes using phase-only modulation. Existing methods often suffer from the speckle noise introduced by random phase modulation, high computational costs, or reduced spa...

Stochastic order-independent transparency enables efficient and elegant rendering of primitive-based radiance fields like 3D Gaussian Splatting models, but remains impractical due to the inherent visible noise in the output. We propose a principled approach to minimize high-frequency noise, addressing its sources at th...

360° images, defined on a sphere, are widely used in immersive applications, but their equirectangular projection introduces distortions, especially near the poles, while the equatorial region is most perceptually important. This paper adapts the HiFiC model to ${360}^{{\circ}}$ imagery through three changes: (i) repla...

3D Gaussian Splatting has become an effective representation for real-time novel view synthesis by optimizing explicit 3D Gaussian primitives from a set of posed images. A key component of this framework is adaptive density control, where Gaussians are cloned, split, or pruned during training to improve scene coverage...

Gaussian Splatting has emerged as a prominent technique in computer vision and graphics, enabling high-fidelity scene reconstruction from a vast collection of 3D Gaussian primitives. Each primitive's appearance is governed by a viewindependent opacity parameter and a view-dependent color derived from spherical harmonic...
