ObjectMover: Generative Object Movement with Video Prior
Simple as it seems, moving an object to another location within an image is,
in fact, a challenging image-editing task that requires re-harmonizing the
lighting, adjusting the pose based on perspective, accurately filling occluded
regions, and ensuring coherent synchronization of shadows and reflections while
maintaining the object identity. In this paper, we present ObjectMover, a
generative model that can perform object movement in highly challenging scenes.
Our key insight is that we model this task as a sequence-to-sequence problem
and fine-tune a video generation model to leverage its knowledge of consistent
object generation across video frames. We show that with this approach, our
model is able to adjust to complex real-world scenarios, handling extreme
lighting harmonization and object effect movement. As large-scale data for
object movement are unavailable, we construct a data generation pipeline using
a modern game engine to synthesize high-quality data pairs. We further propose
a multi-task learning strategy that enables training on real-world video data
to improve the model generalization. Through extensive experiments, we
demonstrate that ObjectMover achieves outstanding results and adapts well to
real-world scenarios.
