AI总结:

针对现有全景合成技术语义引导难、直接套用2D方法易失真的问题,提出HORIZON框架,通过球面建模解决畸变与边缘问题,支持图文语义控制与并行解码生成高分辨率全景,性能优于现有方法。

摘要:

全景图合成致力于打造引人入胜的360度视觉景观,让用户沉浸于虚拟世界的核心场景。然而,当前的全景合成技术在实现内容生成过程的语义引导方面面临挑战。尽管近期视觉合成领域的突破已为2D平面图像的语义控制解锁了可能,但将这些方法直接应用于全景合成会导致内容失真。本研究提出了一种创新的高分辨率全景图生成框架,通过精巧的球面建模巧妙解决了球面畸变与边缘不连续问题。我们的开创性方法支持用户通过图像和文本输入实现语义控制,同时利用并行解码优化高分辨率全景图的生成流程。我们在多种室内外数据集上对方法进行了严格评估,结果表明其在定量与定性性能指标上均优于近期相关工作。本研究将全景合成的可控性、效率与保真度提升至新水平。

英文摘要:

Panorama synthesis endeavors to craft captivating 360-degree visual landscapes, immersing users in the heart of virtual worlds. Nevertheless, contemporary panoramic synthesis techniques grapple with the challenge of semantically guiding the content generation process. Although recent breakthroughs in visual synthesis have unlocked the potential for semantic control in 2D flat images, a direct application of these methods to panorama synthesis yields distorted content. In this study, we unveil an innovative framework for generating high-resolution panoramas, adeptly addressing the issues of spherical distortion and edge discontinuity through sophisticated spherical modeling. Our pioneering approach empowers users with semantic control, harnessing both image and text inputs, while concurrently streamlining the generation of high-resolution panoramas using parallel decoding. We rigorously evaluate our methodology on a diverse array of indoor and outdoor datasets, establishing its superiority over recent related work, in terms of both quantitative and qualitative performance metrics. Our research elevates the controllability, efficiency, and fidelity of panorama synthesis to new levels.
