Polarization-difference imaging (PDI) has been shown to yield an impro
vement in the qualitative and quantitative detectability of objects in
scattering media. In this investigation, PDI and conventional, polari
zation-blind imaging are combined to yield a novel representational sc
heme generally suitable for detection of targets having a low degree o
f linear polarization and specifically suitable for detection and disc
rimination of weakly polarizing targets in scattering media. This repr
esentational scheme meets several general criteria for optimization of
the presentation of low-signal image information to human observers a
nd takes specific advantage of the properties of the opponent-color co
ding used by the human visual system. (C) 1998 Optical Society of Amer
