一种新型全息图表示方法 CVQPG 超越现有技术
Hologram Representation via Quadratic Phase Gaussian Splatting
朋友，DeepSeek 新出的 CVQPG 全息图表示方法，能提升重建质量，比现有技术好 0.19dB 到 0.33dB。
我们提出了一种名为 CVQPG 的新方法，它使用二次相位函数替代了 2D 高斯表示，并增加了可学习参数来控制曲率。在平均 RGB 和灰度值上，该方法比现有方法高出 0.19 dB 和 0.33 dB。我们的频率域分析表明，CVQPG 成功保留了自然图像的中到高频部分。
Hologram Representation via Quadratic Phase Gaussian Splatting
We introduce Complex-Valued Quadratic Phase Gaussian (CVQPG), a novel hologram representation method that replaces standard 2D Gaussian representations used in 2D Gaussian Splatting with 2D quadratic phase functions. CVQPG incorporates additional learnable parameters to control the curvature of these bases. We evaluate our approach against state-of-the-art methods, exceeding the visual quality by +0.19 dB (RGB) and +0.33 dB (grayscale) on average in holographic reconstructions. Specifically, our equal parameter count evaluations show that modulating the primitive's wavefront is an effective and lightweight enhancement for hologram representations. In addition, our frequency domain analysis illustrates that CVQPG has successfully preserved the mid-to-high frequency band of natural images.
