Mutual Motion Camouflage in 3 D ⋆
Motion camouflage is a type of pursuit strategy observed in nature. In this paper, we show that when a pair of autonomous agents, modeled as particles in three dimensions, engage in mutual motion camouflage, their dynamically coupled trajectories exhibit geometrically interesting structure, of possible relevance to applications such as surveillance.
متن کاملSteering laws for motion camouflage
Motion camouflage is a stealth strategy observed in nature. We formulate the problem as a feedback system for particles moving at constant speed, and define what it means for the system to be in a state of motion camouflage. (Here we focus on the planar setting, although the results can be generalized to three-dimensional motion.) We propose a biologically plausible feedback law, and use a high...
متن کامل3D Camouflage in an Ornithischian Dinosaur
Countershading was one of the first proposed mechanisms of camouflage [1, 2]. A dark dorsum and light ventrum counteract the gradient created by illumination from above, obliterating cues to 3D shape [3-6]. Because the optimal countershading varies strongly with light environment [7-9], pigmentation patterns give clues to an animal's habitat. Indeed, comparative evidence from ungulates [9] show...
متن کاملThe mathematics of motion camouflage.
Motion camouflage is a strategy whereby an aggressor moves towards a target while appearing stationary to the target except for the inevitable change in perceived size of the aggressor as it approaches. The strategy has been observed in insects, and mathematical models using discrete time or neural-network control have been used to simulate the behaviour. Here, the differential equations for mo...
متن کامل1 Paper : Motion Camouflage Review
This paper seeks to present and comment upon the ideas and implementations of motion camouflage research. The primary paper reviewed here is the explanation of an experiment (masquerading as a computer game) done on humans in order to establish whether human beings are deceived by motion camouflage. Section 1 will introduce the concepts of camouflage and motion camouflage in particular. Section...
