- Abstract
- A fast selective-intra mode search algorithm based on the rate-distortion (RD) cost for an inter-frame is proposed for H.264/AVC video encoding. In addition to the inter-mode search procedure with variable block size, an intra mode search causes a significant increase in the complexity and computational load for an inter-frame. To reduce the computational load of the intra mode search at the inter-frame, the RD costs of the neighborhood mac-roblocks (MBs) for the current MB are used and we propose an adaptive thresholding scheme for skipping intra mode search. For the IPPP sequence type, the overall encoding time can be reduced up to 40% and 42% for the IBBPBBP sequence type through comparative analysis of experimental results with JM reference software. © 2006 IEEE.
