Excited to share our work at #CVPR2025! 👁️IRIS estimates accurate surface material, spatially-varying HDR lighting, and camera response function given a set of LDR images! It enables realistic, view-consistent, and controllable relighting and object insertion. (links in 🧵)

What if you could control the weather in any video — just like applying a filter? Meet WeatherWeaver, a video model for controllable synthesis and removal of diverse weather effects — such as 🌧️ rain, ☃️ snow, 🌁 fog, and ☁️ clouds — for any input video.

🎬Imagine creating professional visual effects (VFX) with just words! We are excited to introduce AutoVFX, a framework that creates realistic video effects from natural language instructions! This is a cool project led by Hao-Yu, and we will present it at #3DV 2025!

✨What if we could transform a daytime driving video into a realistic nighttime scene—without ever stepping outside again? We introduce UrbanIR, a neural rendering framework for 💡relighting, 🌃nighttime simulation, and 🚘 object insertion—all from a single video of urban scenes!

How do we go beyond colors and recover the intrinsic scene properties? 🤔 👁️ IRIS: Inverse Rendering of Indoor Scenes IRIS estimates accurate material, lighting, and camera response functions given a set of LDR images, enabling photorealistic and view-consistent relighting and object insertion.
