How does an animal conceal itself from visual detection by other animals? This review
paper seeks to identify general principles that may apply in this broad area. It considers …

Camouflage–adaptations that prevent detection and/or recognition–is a key example of
evolution by natural selection, making it a primary focus in evolutionary ecology and animal …

As a typical cyber-physical system, networked unmanned aerial vehicles (UAVs) have
received much attention in recent years. Emerging communication technologies and high …

This study reports on experiments on falcons wearing miniature videocameras mounted on
their backs or heads while pursuing flying prey. Videos of hunts by a gyrfalcon (Falco …

Motion is a crucial part of the natural world, yet our understanding of how animals avoid
predation whilst moving remains rather limited. Although several theories have been …

Much of the existing face recognition systems operate in 2D. As the search for improved
recognition performance intensifies, alternative methods, eg, 3D, are under consideration …

The 'evolutionary arms race'between predator and prey is responsible for many
physiological, morphological, and behavioural adaptations and some of the most compelling …

Motion estimation from image sequences, called optical flow, has been deeply analyzed by
the scientific community. Despite the number of different models and algorithms, none of …

The paper focuses on video monitoring of a moving ground target using an unmanned aerial
vehicle (UAV). The aim is to navigate the UAV so that it is able to monitor the target while …

Protection of wild animals relies on understanding the interaction between the animals and
their environment. With the ability to rapidly access rugged areas, aerial monitoring by …
