Paper Abstract

In this paper, we propose a reduced complexity block-matching motion estimation algorithm for an MPEG video coder. This algorithm consists of a layered structure and hence does not converge to a local optimum. Most importantly, it employs a simple matching criterion, namely, the modified pixel difference classification (MPDC) and hence results in a reduced computational complexity. The MPEG video coder has been simulated using the proposed layered structure MPDC algorithm (LSA-MPDC). Simulation results indicate that the LSA- MPDC algorithm achieves a good performance for both slow and fast moving sequences. In addition, the hardware implementation of the LSA-MPDC algorithm is very simple because of the binary operations used in the matching criteria.
