Interlaced digital video input filter/decimator and/or expander/interpolator filter

摘要

Reduction of storage capacity required by one dimensional digital filter/decimator and/or expander/interpolation filter for spatially filtering that given dimension of a scanned two-dimensional image, represented by a temporal video signal, which is orthogonal to raster scan lines. Such filter devices are particularly suitable for use in Burt Pyramid image processing systems.
