This is a continuation in part of application Ser. The need for this invention arises out of the present state of the art of military camouflage in the visible light spectrum. This invention is designed for the purpose of concealing both stationary and moving objects from view. The term "cloaking" as used in the title of this invention and elsewhere herein refers to concealing such objects. Such techniques are rather primitive and do little to conceal a moving object as it is not possible with present fixed state camouflage techniques to cause an object to continually blend in with a changing background.

Military camouflage

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 probably more common than rapid changes, yet less studied. We discuss three key areas of colour change and camouflage. First, we review the mechanisms underpinning colour change and developmental plasticity for camouflage, including cellular processes, visual feedback, hormonal control and dietary factors.

Thresholding has created to be a well-known technique used for binarization of document images. Thresholding is further divide into the global and local thresholding technique. Noise reduction: The noise, introduced by the optical scanning device or the writing instrument, causes disconnected line segments, bumps and gaps in lines, filled loops etc. The distortion including local variations, rounding of corners, dilation and erosion, is also a problem. Prior to the character recognition, it is necessary to eliminate these imperfections.

Military camouflage is the use of camouflage by an armed force to protect personnel and equipment from observation by enemy forces. In practice, this means applying colour and materials to military equipment of all kinds, including vehicles, ships, aircraft, gun positions and battledress , either to conceal it from observation crypsis , or to make it appear as something else mimicry.

In that war, long-range artillery and observation from the air combined to expand the field of fire, and camouflage was widely used to decrease the danger of being targeted or to enable surprise. As such, military camouflage is a form of military deception.
