SHARP

SHARP is a cutting-edge approach to photorealistic view synthesis that operates in less than a second. By utilizing a single image, SHARP generates a 3D Gaussian representation of the scene, enabling real-time rendering of high-resolution images. This technology showcases robust performance and sets new benchmarks in the field of view synthesis.

1. Fast Synthesis

   SHARP synthesizes a photorealistic 3D representation from a single photograph in under a second on a standard GPU, significantly enhancing the efficiency of view synthesis.

2. High-Resolution Rendering

   The synthesized representation supports high-resolution rendering of nearby views, delivering sharp details and fine structures at over 100 frames per second.

3. Metric Representation

   The 3D Gaussian representation produced by SHARP is metric, allowing for absolute scale and supporting metric camera movements, which is essential for realistic scene navigation.

4. Zero-Shot Generalization

   Experimental results indicate that SHARP demonstrates robust zero-shot generalization across various datasets, making it versatile and adaptable to different scenarios.

5. State-of-the-Art Performance

   SHARP sets new records on multiple datasets, reducing LPIPS by 25–34% and DISTS by 21–43% compared to previous models, while also decreasing synthesis time by three orders of magnitude.
