2-D IIR digital filters for deinterlacing of video signals
Q.S. Gu, L.C.K. Lee, M.N.S. Swamy · 2002
Investigates the application of 2D IIR digital filters for deinterlacing of video signals. A special class of diamond filters is presented, which employs only two coefficients and has approximately zero-phase response. The implementation of this filter is very efficient and the stability is guaranteed even under finite arithmetic conditions. This filter is tested with a group of sequences. Very promising results are obtained.>
