Inter-picture prediction in HEVC can be seen as a steady improvement and generalization of all parts known from previous video coding standards, e.g. H.264/AVC. The motion vector prediction was enhanced with advanced motion vector prediction based on motion vector competition. An inter-prediction block merging technique significantly simplified the block-wise motion data signaling by inferring ...

The paper presents analysis of frame partitioning in the next generation video coding standard HEVC. Complex study on frequency of the particular coding unit, prediction unit and transform unit sizes selection made by the encoder compliant with HEVC technology is included. General conclusions based on extensive experiments for HD video sequences are presented. Such knowledge may be the first st...

Similar to previous video coding standards, transform and quantization are employed in the most recent video coding standard High Efficiency Video Coding (HEVC), and there exist a large number of transform coefficients being quantized to zeros. In order to reduce the computations in transform and quantization, a novel prediction algorithm is designed to early detect all-zero 4 4 blocks prior to...

Using Focus of Attention (FoA) as a perceptual process in image and video compression belongs to well-known approaches to increase coding efficiency. It has been shown that foveated coding, when compression quality varies across the image according to region of interest, is more efficient than the alternative coding, when all region are compressed in a similar way. However, widespread use of su...

Video compression with improved visual quality and with temporal redundancy reduction is a challenging task. Video coding standards such as H.261/3, MPEG-1/2/4 and H.264/AVC use motion estimation (ME) scheme to remove temporal redundancy which significantly improves the coding efficiency. However, the peak signal-to-noise ratio is less. A new video coding method is proposed based on Singular Va...

It is only a matter of time before High Dynamic Range (HDR) video content becomes commercially available. It is necessary, therefore, to develop proper video compression standards that address the peculiarities of this content and enable the introduction of this technology to the consumer market. So far there is no dedicated standard for HDR content. This paper investigates the performance of t...

This paper presents a modified deblocking filter for depth video coding in the 3D video coding extension of High Efficiency Video Coding (3D-HEVC). The conventional 3D video coding extension of HEVC (3D-HEVC) employs a deblocking filter and sample adaptive offset (SAO) in the loop filter in which both tools are applied to color video coding only. Nevertheless, the deblocking filter can smooth o...
