چکیده
The paper presents an architecture for fast mode decision algorithm in H.264/AVC for 4x4 intra-prediction. This algorithm is based on the inherent symmetry existing in the spatial prediction modes. This algorithm gives a faster way of calculating sum of absolute differences (SADs) for all modes of intra prediction. So, a significant computational savings can be achieved. Synthesis results confirmed that the proposed architecture is able to process HD videos (1280x720) at 30 fps as well as 60 fps and Full HD videos (1920x1088) at 30 fps in ASIC platform and maximum frequency achieved is 63 MHz.

The rate-distortion optimization (RDO) method in the H.264/AVC encoder is an informative technology that improves the coding efficiency, but increases the computational complexity. In this letter, a fast Intra mode decision algorithm using DCT (Discrete Cosine Transform) coefficients distribution is proposed to reduce the H.264 encoder complexity.

متن کاملFast Intra Mode Decision Algorithm for H264/AVC HD Baseline Profile Encoder
The high performance of H.264/AVC video encoder is accompanied with a wide computation complexity especially for high definition (HD) video sequences. One of the major H.264/AVC features to be optimized is the mode decision for both inter and intra prediction. Thus, based on high correlation observed between selected inter prediction mode and intra mode decision, a fast intra mode decision algo...

501 Abstract—In the H.264/ AVC video coding standard, the intra-prediction coding with various block sizes offers a considerably high improvement in coding efficiency compared to previous standards. In order to achieve this, H.264/AVC uses the Rate-distortion optimization (RDO) technique to select the best intra-prediction mode for a macroblock, and it brings about the drastic increase of the c...

Two fast mode decision methods for intra prediction in H.264 are proposed in this work to reduce the encoder complexity. The first method, the so-called two-level fast Intra4x4 mode decision, is based on the idea of reducing possible candidate directions of a 4x4 luma block in Intra4x4 mode decision. The second method enables an early selection of suitable 4x4 or 16x16 luma partitions of a give...
