Abstract

An outline for an Extended Color Acquisition joint Model (ECAM) that combines the European TRM4/Visible- Reflectivity Category model with a human perception color difference metrics, enables the Detection, Recognition, Identification (DRI) range performance prediction of color imagers. The prediction of objects acquisition ranges is enabled by applying the TRM model for a color imaging system combined with human observer perceived difference technique. The new concept suggests objects' DRI ranges prediction model of a color image that are treated with two different successive approaches: A physical/hardware 'zone' that includes a colored 4-bar scheme that represents the target and background object, the atmosphere, an imaging color camera and a display in which TRM4 – reflective mode, is applied independently for each of the 3 primary colors. The computation steps in this section are very similar to TRM4-reflective mode described in the Fraunhofer IOSB Technical report 2016/09 -TRM4.v2. A human perception 'zone' where the eye/brain system is involved: the emerged photons from the display are absorbed and processed by a human observer and an image color difference metrics is applied. This work applies a technique for comparing original image and its reproduction to evaluate the difference between target and background represented by a two color standard 4-bar shape, observed at a given range, as captured and presented by a color camera with a color display. The S-SCIELAB metrics that reflects the spatial frequency response to different colors combined with CIEDE2000 difference technique are applied to calculate the perceived difference between a target and a background at each range.
