Abstract
For a feasible calculation of filters for the subband coding of picture sequences with linequincunx subsampling, a coordinate transformation of the sampling raster is proposed. With the new coordinates, the linequincunx subsampling becomes a simple quincunx subsampling without interlace. This facilitates the mathematical derivation of three-dimensional perfect reconstruction filters
