Median-based quincunx interpolation filtering
Timo Huuhtanen · 2005
This paper considers median-based interpolation filters for video signal processing. The application is sampling structure conversion from a quincunx sampling lattice into a rectangular, higher-density sampling lattice. The filter performance is estimated utilizing local step edge and line models. Good detail preservation was achieved with a Linear Median Hybrid (LMH) filter with a simple recursive subfilter. This filter has also small filtering mask, which makes the implementation easy.
