Paper Abstract

This paper presents different imaging interpolation methods implemented for the division of focal plane polarization imaging sensor. The targeted polarization imaging sensor is a CCD based sensor with 1-Mega pixels resolution operating from 400nm to 1050nm wavelength. The five interpolation methods considered in this paper are: bilinear, weighted bilinear, bicubic spline, an approximated bicubic spline and a bicubic interpolation method. Test images of the five different interpolation methods as well as numerical error analysis are presented. Based on the comparison results, the full frame bicubic spline interpolation achieves the best performance for polarization images.
