Camouflage therapy has been used for permanent contour and pigmentary defects including telangiectasias, vitiligo, lentigines, nevi, atrophic scars and burn scars. The goal of the therapy is to provide new and innovative ways to normalize the appearance of patients with abnormalities. A variety of cosmetic techniques are used to assist these patients in making their irregularities as inconspicu...

Camouflage in marine environments requires matching all of the background optical properties: spectral, intensity and polarization components─ all of which can change dynamically in space and time. Current research suggests that polarization detection is more sensitive than other conventional detection methods in scattering media such as the ocean, hence underscoring the need to develop polariz...

Camouflage is frequently used by animals and humans (usually for military purposes) in order to conceal objects from visual surveillance or inspection. Most camouflage methods are based on superpositioning multiple edges on the object that is supposed to be hidden, such that its familiar contours and texture are masked. In this work, we present an operator, (Darg), that is applied directly to t...

We present an alternative approach to create digital camouflage images which follows human’s perception intuition and complies with the physical creation procedure of artists. Our method is based on a two-scale decomposition scheme of the input images. We modify the large-scale layer of the background image by considering structural importance based on energy optimization and the detail layer b...

Martin Stevens is Associate Professor of Sensory and Evolutionary Ecology at the University of Exeter. He did his PhD at Bristol University on bird vision and animal camouflage, and then undertook several fellowships at Cambridge University before moving to Exeter in 2013. His work has focussed on animal coloration, vision, and methods to quantify visual signals, especially image analyses. This...

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...
