Abstract
A fast intramode SKIP detection algorithm based on the rate-distortion (RD) cost for an interframe (P slices) is proposed for H.264/AVC video encoding. There are three types of intrapredictions according to profiles. These are 16 × 16 and 4 × 4 intrapredictions for luminance and an 8 × 8 intraprediction for chroma. For the high profile, an 8 × 8 intraprediction is added for luminance. The 4 × 4 prediction mode has nine prediction directions with four directions for 16 × 16 and 8 × 8 luma, and 8 × 8 chrominance. In addition to the intermode search procedure, an intramode search causes a significant increase in the complexity and computational load for an interframe. To reduce the computational load of the intramode search at the interframe, the rate-distortion (RD) costs of the neighborhood macroblocks (MBs) for the current MB are used, and we propose an adaptive thresholding scheme for the intraSKIP extraction. © 2006 Society of Photo-Optical Instrumentation Engineers.
