AI Executive Summary
Video object removal is a complex task aimed at eliminating dynamic target objects and their visual effects, such as deformation, shadows, and reflections, while restoring seamless backgrounds. Existing diffusion-based video inpainting and object removal methods can remove objects but often struggle to erase these effects and synthesize coherent backgrounds.
To address these issues, researchers introduced the VOR (Video Object Removal) dataset, a large-scale dataset providing diverse paired videos, each consisting of one video where the target object is present with its effects and a counterpart where the object and effects are absent, with corresponding object masks. VOR contains 60K high-quality video pairs from captured and synthetic sources, covering five effects types and spanning a wide range of object categories as well as complex, dynamic multi-object scenes.
Building on VOR, researchers proposed EffectErase, an effect-aware video object removal method that treats video object insertion as the inverse auxiliary task within a reciprocal learning scheme. The model includes task-aware region guidance that focuses learning on affected areas and enables flexible task switching. An insertion-removal consistency objective encourages complementary behaviors and shared localization of effect regions and structural cues.
Trained on VOR, EffectErase achieves superior performance in extensive experiments, delivering high-quality video object effect erasing across diverse scenarios. Experimental results show that EffectErase significantly outperforms existing methods in effect removal accuracy and background synthesis coherence.
Nevertheless, EffectErase may underperform in videos with extreme lighting conditions, and its real-time performance in some highly dynamic scenes needs improvement. Future research directions include exploring its application in real-time video processing and expanding the VOR dataset to cover more effect types and scenarios.
Deep Analysis
Background
Video object removal is a crucial topic in computer vision, aiming to eliminate unwanted dynamic target objects and their associated visual effects, such as deformation, shadows, and reflections, while restoring seamless backgrounds. Traditional methods often rely on static image inpainting techniques, which face challenges when applied to dynamic videos. In recent years, diffusion-based models using deep learning have made some progress in video inpainting and object removal, but these methods often struggle to completely erase object visual effects and synthesize coherent backgrounds. Additionally, the lack of a comprehensive dataset that systematically captures common object effects across varied environments further limits progress in this field.
Core Problem
The core problem of video object removal is effectively erasing target objects and their visual effects while maintaining background coherence. The challenge lies in the complex and variable nature of visual effects, including deformation, shadows, and reflections, which manifest differently across environments. Moreover, existing methods often struggle to maintain background coherence and completely erase visual effects in multi-object dynamic scenes.

Abstract
Video object removal aims to eliminate dynamic target objects and their visual effects, such as deformation, shadows, and reflections, while restoring seamless backgrounds. Recent diffusion-based video inpainting and object removal methods can remove the objects but often struggle to erase these effects and to synthesize coherent backgrounds. Beyond method limitations, progress is further hampered by the lack of a comprehensive dataset that systematically captures common object effects across varied environments for training and evaluation. To address this, we introduce VOR (Video Object Removal), a large-scale dataset that provides diverse paired videos, each consisting of one video where the target object is present with its effects and a counterpart where the object and effects are absent, with corresponding object masks. VOR contains 60K high-quality video pairs from captured and synthetic sources, covers five effects types, and spans a wide range of object categories as well as complex, dynamic multi-object scenes. Building on VOR, we propose EffectErase, an effect-aware video object removal method that treats video object insertion as the inverse auxiliary task within a reciprocal learning scheme. The model includes task-aware region guidance that focuses learning on affected areas and enables flexible task switching. Then, an insertion-removal consistency objective that encourages complementary behaviors and shared localization of effect regions and structural cues. Trained on VOR, EffectErase achieves superior performance in extensive experiments, delivering high-quality video object effect erasing across diverse scenarios.
