Abstract: Camouflage in nature seems to arise from competition between predator and prey. To survive, predators must find prey, and prey must avoid being found. This work simulates an abstract model of that adversarial relationship. It looks at crypsis through evolving prey camouflage patterns (as color textures) in competition with evolving predator vision. During their "lifetime" predators learn to better locate camouflaged prey. The environment for this 2D simulation is provided by a set of photographs, typically of natural scenes. This model is based on two evolving populations, one of prey and another of predators. Mutual conflict between these populations can produce both effective prey camouflage and predators skilled at "breaking" camouflage. The result is an open source artificial life model to help study camouflage in nature, and the perceptual phenomenon of camouflage more generally.

CNCA: Toward Customizable and Natural Generation of Adversarial Camouflage for Vehicle Detectors [19.334642862951537]
We propose a Customizable and Natural Camouflage Attack (CNCA) method by leveraging an off-the-shelf pre-trained diffusion model. Our method can generate natural and customizable adversarial camouflage while maintaining high attack performance.

The Making and Breaking of Camouflage [95.37449361842656]
We show that camouflage can be measured by the similarity between background and foreground features and boundary visibility. We 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.

Predator-prey survival pressure is sufficient to evolve swarming behaviors [22.69193229479221]
We propose a minimal predator-prey coevolution framework based on mixed cooperative-competitive multiagent reinforcement learning. Surprisingly, our analysis of this approach reveals an unexpectedly rich diversity of emergent behaviors for both prey and predators.

Camouflaged Image Synthesis Is All You Need to Boost Camouflaged Detection [65.8867003376637]
We propose a framework for synthesizing camouflage data to enhance the detection of camouflaged objects in natural scenes. Our approach employs a generative model to produce realistic camouflage images, which can be used to train existing object detection models. Our framework outperforms the current state-of-the-art method on three datasets.

Strategic Preys Make Acute Predators: Enhancing Camouflaged Object Detectors by Generating Camouflaged Objects [107.47530456103758]
Camouflaged object detection (COD) is the challenging task of identifying camouflaged objects visually blended into surroundings. We draw inspiration from the prey-vs-predator game that leads preys to develop better camouflage and predators to acquire more acute vision systems. We introduce a novel COD method, called Internal Coherence and Edge Guidance (ICEG), which introduces a camouflaged feature coherence module.

Simultaneously Localize, Segment and Rank the Camouflaged Objects [55.46101599577343]
Camouflaged object detection aims to segment camouflaged objects hiding in their surroundings. We argue that explicitly modeling the conspicuousness of camouflaged objects against their particular backgrounds can lead to a better understanding about camouflage and evolution of animals. We present the first ranking based COD network (Rank-Net) to simultaneously localize, segment and rank camouflaged objects.
