CVPR 2025 HighlightGenerative Photography: Scene-Consistent Camera Control for Realistic Text-to-Image Synthesis

Control the camera, preserve the world.

Scene-consistent camera control for realistic text-to-image synthesis.

ProblemExisting generative models do not understand the physical meaning of camera intrinsics or preserve scene consistency.
IdeaDimensional lifting disentangles scene and camera; differentiated parameter injection enables fine-grained control.
ResultControl bokeh, focal length, shutter speed, and color temperature while preserving scene identity.
Bokeh rendering result Focal length control result Shutter speed control result Color temperature control result

Under ReviewOptiWorld: Optimal Control for Video World Generation under Physical Constraints

Plan a better future, then render it.

OptiWorld makes video world models choose better futures: safer, smoother, more efficient, and physically constrained motions before rendering.

ProblemCurrent video generation lacks proactive understanding and control, producing results that may be unsafe or inefficient.
IdeaIntroduce classical optimal control before video rendering.
ResultSafer, more efficient goal-conditioned I2V and video refinement.
