Abstract

In this paper, we purpose interpolation technique for a 3-micropolarizer design of division of focal plane (DoFP) image sensor based on polarization residuals. The super pixel of 3-micropolarizer division of focal plane (DoFP) polarization image sensor records the first three (S0, S1, S2) at each frame but each specific pixel within the superpixel has a somewhat different field of view. The missing polarization information creates edges and nonconformities in the polarized images. The micropolarizer consists of a 3-micropolarizer filter array of 0°, 90°, and 135°. The DoFP image sensor output image remains 2D. We will demonstrate the performance of the algorithm on the intensity, degree of linear polarization (DoLP) and angle of linear polarization (AoP) images. We will further demonstrate that our proposed algorithm can estimate suitable missing polarization information for low-resolution images to generate high-resolution images.
