Fast 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...
متن کاملArchitecture for H.264 Intra Prediction Fast Mode Decision Algorithm
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 confi...
متن کاملFast Intra Prediction Mode Decision Algorithm for HEVC
This paper proposes a novel fast intra-prediction algorithm that exploits the Sobel operator to replace the Hadamard transform used in the Rough Mode Decision (RMD) process of intra prediction in High Efficiency Video Coding (HEVC). First, the Sobel operator is used to calculate the vector direction of each pixel. A judgment is then made on which prediction mode the vector belongs to, and a his...
متن کاملFast Intra Mode Decision for Depth Map coding in 3D-HEVC Standard
three dimensional- high efficiency video coding (3D-HEVC) is the expanded version of the latest video compression standard, namely high efficiency video coding (HEVC), which is used to compress 3D videos. 3D videos include texture video and depth map. Since the statistical characteristics of depth maps are different from those of texture videos, new tools have been added to the HEVC standard fo...
متن کاملA Fast Depth Intra Mode Selection Algorithm
For the purpose of reducing the complexity of depth intra coding, a fast intra prediction mode decision algorithm is proposed. First, the fast decision of depth modeling modes (DMMs) is obtained by using Laplace Operator detection method. Second by using the correlation between the wedgelet pattern and texture features, only the wedgelet patterns, which are related to the intra angle mode, is t...
