“…A standard glass surface reference is shown in the middle for texture identification between TOB (camouflage-treated textiles) and CB materials. A 1 and A 2 identify similar surface of TOB as specular R. B 1 and B 2 indicate dissimilar surface of TOB as diffuse R. C 1 and C 2 depict the combination of specular and diffuse R. The electron interactions of specular and rough surfaces are not same due to polarization behavior of light R. 22,32…”

Chromatic and achromatic (AC) assessments of camouflage textiles have been critical to the defense researchers for concealment, detection, recognition, and identification (CDRI) of target signature against multidimensional combat background (CB). AC assessment and camouflage measurement techniques are simulated and experimented for assessment of camouflage textiles against CB. This model has been demonstrated for color measurement spectrophotometer, scanning electron microscopy (SEM), digital imaging, hyperspectral imaging, and image processing software (ImageJ) for the advancement and establishment of AC camouflage textiles assessment. The chromatic variations of 48 artificial target objects (TOBs) have been synthesized by image processing; the technique can be implemented for defense CB-CDRI assessment. Microstructural variation versus optical signal of woodland, desertland and stoneland CB materials have been elucidated by SEM magnification. The achromatic variation of CB materials have been demonstrated for the replacement of optical signal against modern remote sensing device to the imaging sensor. Color difference (Δ E), microstructural variations, pixel variations to imaging signal and standard deviation of CB materials have been represented for remote sensing surveillance of defense applications against TOB-CB-CDRI. Technical simulation of color, texture, gloss, and pixel intensity has been derived for AC-CDRI assessment of camouflage textiles in TOBs-CB environment.

“…The acquisition of target polarization information effectively expands the information dimension and enhances the texture features to effectively improve the accuracy of target detection and identification. Therefore, polarization detection technology can be widely used in target detection [1], [2], medical diagnosis [3], [4] and military applications [5], [6], etc.…”

Scattering polarization properties are one of the main characteristics of a target. Different material types of the target surface can be expressed by the scattering polarization properties, and the use of polarization to characterise the target more effectively is a highly interesting topic. However, the existing polarized bidirectional reflection distribution function (pBRDF) based on microfacet theory for modelling light transmission over rough surfaces is not general. Modelling the scattering phenomena accurately on microsurfaces from a single specularly polarized reflection to full consideration of diffuse polarization remains a challenging task. In this work, we further introduce a directional diffuse reflection lobe to completely define the polarization properties of light in scattering, and revisit the microsurface in the masking and shadowing function part of the model, expanding the traditional symmetric V-groove structure, which is complemented by an asymmetric V-groove structure to improve the accuracy of the model description. We verify through a series of simulations and experiments that our model is in better agreement with the actual truth and that it is more suitable for describing the scattering polarization properties of most targets.
