Abstract :
Field rate up-conversion using adaptive weighted median filtering is described. The weights of the algorithm are adapted according to the output from a motion detector. High-speed VLSI circuit architectures for the computation of weighted median are discussed. A bit-sliced architecture based on a previously introduced bit-serial method, having good expandability and supporting computation of weighted medians, is described
