TRICLOBS portable triband color lowlight observation system

We present the design and first test results of the TRICLOBS (TRI-band Color Low-light OBServation) system The TRICLOBS is an all-day all-weather surveillance and navigation tool. Its sensor suite consists of two digital image intensifiers (Photonis ICU's) and an uncooled longwave infrared microbolometer (XenICS Gobi 384). The night vision...

Towards an optimal color representation for multiband nightvision systems

We present a new Tri-band Color Low-light Observation (TRICLOBS) system The TRICLOBS is anall-day all-weather surveillance and navigation tool. Its sensor suite consists of two digital image intensifiers and an uncooled longwave infrared microbolometer. This sensor suite registers the visual, near-infrared and longwave infrared bands of the...

Presenting nighttime imagery in daytime colours

We present a fast and efficient method to derive and apply natural colours to nighttime imagery from multiband sensors. The colour mapping is derived from the combination of a multiband image and a corresponding daytime colour reference. The mapping optimizes the match between the multiband image and the reference, and yields a nightvision image...

Portable real-time color night vision

We developed a simple and fast lookup-table based method to derive and apply natural daylight colors to multi-band night-time images. The method deploys an optimal color transformation derived from a set of samples taken from a daytime color reference image. The colors in the resulting colorized multiband night-time images closely resemble the...

Method for applying daytime colors to nighttime imagery in realtime

We present a fast and efficient method to derive and apply natural colors to nighttime imagery from multiband sensors. The color mapping is derived from the combination of a multiband image and a corresponding natural color reference image. The mapping optimizes the match between the multiband image and the reference image, and yields a...
