Insect behaviour: Motion camouflage in dragonflies

Most animals can skilfully conceal themselves when stationary, but they may become apparent as soon as they move. Here we use stereo cameras to reconstruct the movements in three dimensions of dragonflies (Hemianax papuensis), and show that these insects actively use motion camouflage to disguise themselves as stationary during territorial aerial manoeuvres. Deployment of this sophisticated technique by the oldest airborne predator tricks the victim's retina into perceiving the stalker as… 
Camouflage and visual perception
The aim is to provide a number of pointers towards issues, which may be of assistance in understanding camouflage and concealment, particularly with reference to how visual systems can detect the shape of complex, concealed objects.
Biomimetic strategies for motion camouflage
The theory of motion camouflage is explored, and an optimal-energy formula for motion camouflaged paths is developed using lagrangian mechanics, and a method for implementing force-based camouflage control into fixed wing aerial robots is discussed.
Avoidance of a moving threat in the common chameleon (Chamaeleo chamaeleon): rapid tracking by body motion and eye use
A chameleon on a perch responds to a nearby threat by moving to the side of the perch opposite the threat, while bilaterally compressing its abdomen, thus minimizing its exposure to the threat.
Bio-Inspired Rendezvous Strategies and Respondent Detections
The feasibilities of applying a bio-inspired rendezvous strategy to free-flying space vehicles and the respondent detections of such motion strategies to prevent orbital collisions are investigated in the local vertical and local horizontal frame.
Pursuit and an evolutionary game
Pursuit is a familiar mechanical activity that humans and animals engage in—athletes chasing balls, predators seeking prey and insects manoeuvring in aerial territorial battles. In this paper, we

On motion camouflage as proportional navigation
Two simpler control mechanisms are hypothesised which, it is shown, can also generate motion camouflage and are an extension of proportional navigation, another interception technique found in nature, and therefore, both animal behaviours seem to be connected.
Biomimetic Drones Inspired by Dragonflies Will Require a Systems Based Approach and Insights from Biology
It is asserted that an optimal flapping wing drone, capable of efficiency in all modes of flight with high performance upon demand, might look somewhat like an abstract dragonfly.


Visual control of flight behaviour in the hoverflySyritta pipiens L.
The visually guided flight behaviour of groups of male and femaleyritta pipiens was filmed at 50 f.p.s. and analysed frame by frame and it was shown that to synchronise the two flies the sideways tracking system must also be operative.

In this paper we consider whether an animal or an agent (a ‘shadower’) can actively camouflage its movements whilst tracking another animal or agent (a ‘shadowee’). It is shown that, under certain
Visual Motion and Its Role in the Stabilization of Gaze
The author examines the role of Visual Motion in the Stabilization of Body Posture in Vertebrates and Vertebrate Retinal Ganglion Cells and the Optokinetic Response in Primates and its Possible Neuronal Substrate.

A new technique for three-dimensional camera calibration for machine vision metrology using off-the-shelf TV cameras and lenses using two-stage technique has advantage in terms of accuracy, speed, and versatility over existing state of the art.
