A new adaptive window‐based guided filtering and interpolation for polarization image demosaicing

This paper presents a new adaptive window-based guided filtering and interpolation for polarization image demosaicing. Considering the correlation between channels, authors use total intensity S0 as guide to of all channels. The is performed with window size selection technique. A novel iterative residual proposed construct accurate full resolution polarization. Experiments are conducted sample images from demosaicking algorithms dataset. Objective evaluations demonstrate that algorithm can reduce root mean squared error by at least 27% over other methods. Subjective visual inspection also verify improvements in clarity objects angle degree linear images.
