Residual interpolation for micropolarizer array patterns of polarization image sensors

In this paper, we have applied residual interpolation to low-resolution polarized images of different micropolarizer patterns for division of focal plane (DoFP) polarization image sensors. We observed the polarization accuracy recovery through visual evaluation of intensity, degree of linear polarization (DoLP) and angle of linear polarization (AoP) images and found that residual interpolation works well on a 4-micropolarizer pattern of a rooster image.
