Traditional smoothing depth DIBR system generates geometric distortion in synthesis virtual view. In this paper, an edge-oriented hole filling algorithm for the DIBR is proposed. The traditional smoothing depth approach is discarded, while hole filling is adapted instead. For natural and smooth hole filling, the edge information around the hole is used in the proposed method. The non-smoothing depth...
The MPEG-4 H.264/AVC video coding standard adopts variable block sizes for inter frame coding to increase compression efficiency. However, to achieve this, the H.264 encoder employs a complex mode decision technique based on rate-distortion optimization (RDO) that requires high computational complexity, which significantly increases the encoder complexity. This paper proposes a fast hierarchal cross...
H.264, MPEG-4 Part 10, is the latest digital video coding standard that is noted for achieving very high data compression by using several new coding features. One of the key features is the intra prediction based on the rate distortion optimization (RDO) procedure, which requires a true encoding of the intra block by trying all intra prediction modes. The computational burden of intra prediction...
In this paper, a fast intra mode decision algorithm based on transform-domain property is proposed to reduce the coding complexity in H.264/AVC encoder. According to the basis patterns for DCT transformation, the 4 times 4 block is first transformed and then the transformed coefficients are utilized to detect the tendency of target block. In comparison to the previous fast mode decision algorithms,...
