A Survey: Fast Inter CU selection algorithms for HEVC
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 3
Abstract
A hybrid quad tree structure in which current CU recursively divided into four equal sized CU’s, is adopted by HEVC. At each decomposition level (depth), the RD cost for each of the following modes, SKIP mode, merge mode, inter 2N × 2N, inter 2N × N, inter N × 2N, inter 2N × nU, inter 2N × nD, inter nL × 2N, inter nR × 2N, inter N × N (only available for the smallest CU), intra 2N × 2N, and intra N × N (only available for the smallest CU) in inter-frame prediction is calculated. Among the all possible depth levels and prediction modes, the one which having least RD cost is selected. These inter CU selection process poses high computational complexity which is main obstacle in implementing HEVC for real time applications. Recently huge research has carried out on reducing computational complexity of HEVC encoders. This paper presents different methods for fast inter CU selection algorithms which reduces the encoding time of HEVC coding process. A survey of these various algorithms and an evaluation of their pros and cons may provide valuable leads for the improvement in HEVC inter-prediction.
