LightGenBench: A Benchmark for 3D Emission Generation

Recent generation methods produce 3D assets with detailed geometry and rich textures. However, these assets are non-emissive: they reflect light but emit none. We study a new task, emission generation: predicting spatially varying RGB emission over a 3D asset's surface from its geometry, non-emissive materials, and a r...

Chehre: An Emoji-Prompted Dataset to Explore Perceptual Flexibility in Video Language Models

Chehre, an emoji-prompted video dataset with a wide range of dynamic facial expressions for exploring perceptual variation, finds that persona prompting can act as a controllable way to shift model perception while helping models better capture the variation observed across human annotators.
