Hong Kong – In a significant leap forward for image editing technology, the University of Hong Kong (HKU) and Adobe Research have jointly announced the development of ObjectMover, a novel AI model poised to redefine how we manipulate images. This groundbreaking technology addresses long-standing challenges in image editing, specifically related to the seamless movement, insertion, and removal of objects within a scene.
(Introduction)
For years, image editing software has struggled to realistically integrate manipulated objects into images. Issues such as inconsistent lighting, unnatural shadows, and object distortion have plagued even the most skilled users. ObjectMover tackles these problems head-on, promising a new era of photorealistic image manipulation.

What is ObjectMover?
ObjectMover is an AI-powered image editing model developed through a collaborative effort between HKU and Adobe Research. Its core function lies in intelligently handling the complexities of object manipulation within images. Unlike traditional methods that often result in jarring inconsistencies, ObjectMover aims to seamlessly integrate moved, inserted, or removed objects, maintaining visual harmony and realism.
Key Features and Capabilities:
- Object Movement: ObjectMover allows users to move objects within an image to a specified location while automatically adjusting related physical effects such as lighting, shadows, and reflections. Crucially, it preserves the identity and characteristics of the moved object, preventing unwanted transformations.
- Object Removal: The model can realistically fill the space left behind by a removed object, intelligently generating background textures and patterns that blend seamlessly with the surrounding environment. Unlike simple content-aware fill tools, ObjectMover avoids introducing irrelevant or artificial elements, ensuring a natural-looking result. It also accurately removes associated light and shadow artifacts.
- Object Insertion: ObjectMover can precisely insert objects into an image, maintaining their original identity and generating consistent lighting and shadow effects that match the environment. This allows for the creation of composite images that appear as though they were captured in a single shot.
The Underlying Technology: Video Prior Transfer
The innovation behind ObjectMover lies in its unique approach to the problem. The model treats object movement as a special case of a two-frame video sequence. By leveraging the cross-frame consistency learning capabilities of pre-trained video generation models, such as diffusion models, ObjectMover effectively transfers this knowledge to the task of image editing.
The model employs sequence-to-sequence modeling, taking as input the original image, the target object image, and a guidance map indicating the desired movement or manipulation. The output is a synthesized image with the object seamlessly integrated into its new context. This video prior transfer technique allows ObjectMover to learn and apply complex relationships between objects and their environment, resulting in more realistic and convincing edits.
(Conclusion)
ObjectMover represents a significant advancement in AI-powered image editing. By leveraging the power of video generation models and employing a novel approach to object manipulation, this technology promises to empower users with unprecedented control and realism in their image editing workflows. The collaboration between HKU and Adobe Research highlights the potential of academic-industry partnerships to drive innovation in artificial intelligence and its applications. Future research could explore expanding ObjectMover’s capabilities to handle more complex scenarios, such as manipulating multiple objects simultaneously or incorporating user-defined artistic styles. The potential impact of ObjectMover on fields ranging from photography and graphic design to visual effects and virtual reality is substantial, heralding a new era of creative possibilities.
