The state-of-the-art video coding standard H.264/AVC achieves significant coding performance improvement by choosing the rate-distortion (RD) optimized encoding mode from a list of candidate modes at the cost of intensive computations, which limits the practical application of H.264/AVC. A number of fast mode decision algorithms have been recently presented in the literature in order to reduce H.264/AVC encoding computations. In this paper, a novel two-dimensional (2D) map based fast mode decision scheme is proposed, which produces a flexible mode checking order for fast mode decision. Experimental results demonstrate that with the proposed algorithm, the computational complexity of H.264/AVC coding is significantly reduced while the video quality and compression efficiency are preserved. © 2008 Springer.
