چکیده
|
For the wireless multimedia sensor network (wmsn), the intraframe video coding is widely used for the robust transmission and computation complexity. though the intraframe algorithm requires much smaller computational complexity than the interframe coding, the amount of computation of the intraframe should be reduced to use wmsn application. in this paper, we propose an intra mode decision algorithm to reduce the computation complexity of intraframe h.264/avc encoders. the proposed algorithm determines the candidate modes and skips the remaining modes based on the smoothness and directional similarity of mb. the simulation results show that the proposed algorithm achieves 18% to 70% reduction in the computational complexity, compared with the various conventional methods.
