IIR digital filters for sampling structure conversion and deinterlacing of video signals

摘要

In this paper, we investigate the application of multidimensional IIR digital filters for video signal processing. The problems of sampling structure conversion and deinterlacing are addressed. A multistage filter structure is then proposed to perform the general conversions among different types of sampling structures. Some simple IIR digital filters are proposed and simulated particularly for the above applications. Some simulation results are also given.
