WiT: Waypoint Diffusion Transformers via Trajectory Conflict Navigation
A pixel-space diffusion framework that uses semantic waypoints to reduce trajectory conflict and improve convergence for ImageNet generation.
About
About Me
I am a direct Ph.D. student at Tianjin University, advised by Prof. Xiaojie Guo. My research focuses on computer vision, especially image generation, diffusion models, and low-level vision. I welcome discussions and collaborations on related research topics.
