Efficient algorithm for H.264/AVC intra frame transcoding
Chien-Da Wu, Yinyi Lin · 2010
Our previous work presents an enhanced SATD-based intra mode decision to improve computation cost while maintaining good coding performance. Based on the enhanced SATD-based intra mode decision, this paper proposes an efficient H.264/AVC intra frame transcoding which utilizes original coded mode type information to eliminate unlikely modes before the enhanced intra mode decision. Both coding and computation performances are compared with complex cascaded pixel domain transcoding (CCPDT) and simple cascaded pixel domain transcoding (SCPDT) algorithms.
