First- and second-order contrast stimuli can be described for the visual, auditory and tactile senses. Similarly, electrosensory contrast patterns vary over large spatial and temporal scales. Fast ...

The disc of red, green, and cyan LEDs gives the device built-in lighting and enhances contrast, letting it clearly detect features other sensors might miss. The Checker detects features on parts, not ...

Painting army vehicles with high contrast geometric patterns -- "dazzle camouflage" -- affects the perception of their speed and thus could make them less susceptible to rocket propelled grenade ...

Laura Kelley receives funding from the People Programme (Marie Curie Actions) of the European Union’s Seventh Framework Programme (FP7/2007-2013). Many animals use the colours and patterns on their ...

Military vehicles painted with high-contrast geometric patterns can perturb enemy combatants’ perception of the vehicle’s speed and therefore the accuracy of any attack. The study represents the first ...
