Camouflage pattern

This has been a bugbear all along, and in the early 1990s we tried to establish how the contours of detection around a buried mine, or mines, looked. The shape we established, I described later, could be as irregular as a camouflage pattern. 

What is important is to note that when the water dried up the spread of TNT remained in that shape. This would explain the so-called camouflage patterns we had determined ten years before. The scientific tests and results obtained in the early 1990s by the old Mechem were never published and only recorded in broad detail. What was shared was the results and developed techniques. 

Editor You discussed the camouflage patterns of leaked explosives in soil and vegetation. How long after the puddles dry are MDDs able to find the scent It would seem that, since animals must be trained with particular suites of molecules, or aromas, that these should match the expected field aromas. Do decomposition products become more important and change over time ... 

One of the most important aspects of camouflage patterns is that the pattern needs to be optimised for the envisaged tactical distance. This was already realised in... 

Purveslab at the Center for Cognitive Neuroscience, Duke University, has published numerous papers on the psychophysical visual effects people experience. One of the most striking examples of how the eye perceives colour in context is described by Lotto and Purves (2000). The discs, described in this paper, are similar to the two cubes with coloured squares (similar to a Rubik s cube) shown on the laboratory s website (Purveslab, 2011). The two cubes look similar, but one is shown in a blue environment, while the other one is shown in a yellow environment. The darkest squares of the cube in the yellow environment are blue. Yellow is the second-lightest colour of the cube in the blue environment. But, when the above-mentioned blue and yellow squares are isolated from their respective environments (taken out of context), all of them have the same colour The reason for this is called colour contrast. Although the spectral returns from the said squares are the same, the perception is that they exist in environments with different illumination, and therefore they elicit different colour stimuli in the brain. Camouflage patterns, with colours exhibiting this kind of behaviour, are effective in a wide range of environments. 

The second forced-choice pairwise comparison method is the Analytical Hierarchy Process (AHP). During a LCJ evalnation the observers only need to state which pattern they perceive as better, while with AHP they also need to state by how much the one design is better than the other. Banmbach has fonnd the AHP to be a more meaningful method to evaluate camouflage patterns (Baumbach, 2008 2010). The first reason for it to be a more effective method is that the result for AHP is expressed on a scale from 0 to 100. The resnlt for LCJ is expressed as values on an open-ended scale, which makes comparison between different test...
