The Making and Breaking of Camouflage

no code implementations ICCV 2023 Hala Lamdouar, Weidi Xie, Andrew Zisserman

We also incorporate the proposed camouflage score into a generative model as an auxiliary loss and show that effective camouflage images or videos can be synthesised in a scalable manner.

Self-supervised Video Object Segmentation by Motion Grouping

no code implementations ICCV 2021 Charig Yang, Hala Lamdouar, Erika Lu, Andrew Zisserman, Weidi Xie

We additionally evaluate on a challenging camouflage dataset (MoCA), significantly outperforming the other self-supervised approaches, and comparing favourably to the top supervised approach, highlighting the importance of motion cues, and the potential bias towards visual appearance in existing video segmentation models.

Betrayed by Motion: Camouflaged Object Discovery via Motion Segmentation

no code implementations23 Nov 2020 Hala Lamdouar, Charig Yang, Weidi Xie, Andrew Zisserman

We make the following three contributions: (i) We propose a novel architecture that consists of two essential components for breaking camouflage, namely, a differentiable registration module to align consecutive frames based on the background, which effectively emphasises the object boundary in the difference image, and a motion segmentation module with memory that discovers the moving objects, while maintaining the object permanence even when motion is absent at some point.
