Objective: The purpose of this study was to compare long-term stability and satisfaction between orthodontic camouflage and orthognathic surgery in treatment of moderate skeletal Class III adults. Materials and Methods: A total of 25 adults females who had been treated with orthodontic camouflage for Class III malocclusions were recalled at least 3 years posttreatment to evaluate stability and ...

The focus of this research project was the development of a procedure by which various alternative camouflage schemes could be developed, and once developed, evaluated. Our approach was to delineate principles of camouflage, for concealment and for deception. Once these principles were uncovered, various combinations of independent variables, each developed from a particular principle were then...

This paper describes a kind of active camouflage system named Optical Camouflage. Optical Camouflage uses the Retro-reflective Projection Technology, a projection-based augmented–reality system composed of a projector with a small iris and a retroreflective screen. The object that needs to be made transparent is painted or covered with retroreflective material. Then a projector projects the bac...

AIM Dental fear and anxiety in early childhood are widely prevalent and contribute to dental problems and behaviour in adulthood. Novel ways to reduce dental fear and anxiety in children are needed. Our aim was to conduct an efficacy trial of a novel Camouflage Syringe to reduce dental fear and anxiety in children. MATERIALS AND METHODS STUDY DESIGN randomised controlled trial of efficacy ...

Camouflage is an attempt to conceal the signature of a target object into the background image. Camouflage detection methods or Decamouflaging method is basically used to detect foreground object hidden in the background image. In this research paper authors presented survey of camouflage detection methods for different applications and areas. © 2012 The Authors. Published by Elsevier B.V. Sele...

Animals from a wide range of taxonomic groups are capable of colour change, of which camouflage is one of the main functions. A considerable amount of past work on this subject has investigated species capable of extremely rapid colour change (in seconds). However, relatively slow colour change (over hours, days, weeks and months), as well as changes arising via developmental plasticity are pro...

Animal coloration has multiple functions including thermoregulation, camouflage, and social signaling, and the requirements of each function may sometimes conflict. Many terrestrial ectotherms accommodate the multiple functions of color through color change. However, the relative importance of these functions and how color-changing species accommodate them when they do conflict are poorly under...

Camouflage is conferred by background matching and disruption, which are both affected by microhabitat. However, microhabitat selection that enhances camouflage has only been demonstrated in species with discrete phenotypic morphs. For most animals, phenotypic variation is continuous; here we explore whether such individuals can select microhabitats to best exploit camouflage. We use substrate ...

Camouflage is one of the most widespread antipredator defences, and its mechanistic basis has attracted considerable interest in recent years. The effectiveness of camouflage depends on the interaction between an animal's appearance and its background. Concealment can therefore be improved by changes to an animal's own appearance, by behaviorally selecting an optimal background, or by modifying...
