Pixel Decimation of RD-Cost Functions in the HEVC Encoder
We present and analyse schemes for the improvement of computational complexity in the current HEVC (High Efficiency Video Coding) standard, by a subsampling of the block-matching distortion cost functions used in the encoding process. HEVC improves on prior standards considerably in coding (compression) efficiency, with a large set-back in time complexity for inter and intra prediction processe...
متن کاملHEVC Encoder Optimization Based on a New RD Model and Pre-Enoding
In this paper, a new Rate Distortion (RD) model based on the content measured by the sum of absolute transformed differences (SATD) is developed. Based on this advanced RD model we propose an encoding optimization method for HEVC codec. First, we perform pre-compression with multiple quantization parameters (QPs) on selected coding modes (SKIP, Inter8x8, Intra8x8) for the current frame and get ...
متن کاملAnalysis of Compressed Data Stream Content in HEVC Video Encoder
In this paper, a detailed analysis of the content of the bitstream, produced by the HEVC video encoder is presented. With the use of the HM 10.0 reference software the following statistics were investigated: 1) the amount of data in the encoded stream related to individual frame types, 2) the relationship between the value of the QP and the size of the bitstream at the output of the encoder, 3)...
متن کاملFast encoder decision for texture coding in 3D-HEVC
As a 3D extension of the High Efficiency Video Coding (HEVC) standard, 3D-HEVC is developed to improve the coding efficiency of multi-view video. However, the improvement of the coding efficiency is obtained at the expense of a computational complexity increase. How to relieve the computational burden of the encoder is becoming a critical problem in applications. In this paper, a fast encoder d...
متن کاملReference frame selection in a hardware-based HEVC encoder
The multiple-reference-frame motion estimation (ME) is one of the features to improve the compression efficiency. However, the computational complexity for prediction increases in proportion to the number of reference frames. This paper proposes the reference frame selection algorithm for a hardware-based HEVC encoder. The integer-ME explores multiple reference frames to find the best one and t...
