Abstract

The motion estimation can choose the most suitable algorithm for different kinds of motion types, formats, and characteristics. The video encoding system can be optimized for quality, speed, and power consumption. In this paper, we propose a reconfigurable approach to a motion estimation algorithm and hardware architecture. The proposed algorithm determines motion type and then selects adapted block-matching algorithm for different kinds of motion sequences. The quality of our algorithm is better than that of the TSS and the BBGDS algorithm, or comparable to the performance of the better of the two, and the computational complexity of our algorithm is significantly less than that of the TSS. We also propose hardware architecture for realizing two kinds of motion estimations in the same hardware. We implemented the flexible and reconfigurable hardware architecture by using address generator unit, delay unit, and parameters and by using the hardware description language (VHDL) and the SYNOPSYS synthesis design tools. We analyze the performance of the algorithm and present adapted algorithm for a low cost real time application.
