The Scalable High Efficiency Video Coding (SHVC) has been proposed to improve the coding efficiency. However, this additional extension generally results an important coding complexity. Several studies were performed to overcome the complexity through algorithmic optimizations that led to an encoding time reduction. In fact, mode decision analysis is imperatively important in order to have an i...

With the rapid developments on multimedia and Internet, more and more images and videos are transmitted and viewed in digital form. Video representation and compression are at the foundation of such kind of multimedia applications. Object-based video coding, also known as the representatives of content-based video coding, has been proposed to represent and compress the foreground and the backgr...

SMART, the acronym of scalable media adaptation and robust transport, is a suite of compression and transmission technologies for efficient, scalable, adaptive, and robust video streaming over the best-effort Internet. It consists of two indispensable parts: SMART video coding and SMART video streaming. The SMART video coding part is an efficient DCT-based universal fine granularity scalable co...

Scalable video coding is important in a number of applications where video needs to be decoded and displayed at a variety of spatial and temporal resolution scales or when resilience to errors is necessary. In this paper, we investigate a temporaldomain approach for resolution scalable video coding. This approach was originally proposed to and since then has been included in the Moving Picture ...

In this work, we present PRISM (Power-efficient, Robust, hIgh-compression, Syndrome-based Multimedia coding), a video coding paradigm based on the principles of coding with side information (which, unlike the classical WynerZiv coding scenario [1], is characterized by an ambiguous state of nature characterizing the side-information [2]). PRISM’s architectural goals are to inherit the low encodi...

An efficient down/upsampling method to compress a depth map efficiently within the high-efficiency video coding (HEVC) framework is presented. A different edge-preserving depth upsampling method is proposed by using both the texture and depth information. We take into account the edge similarity between depth maps and their corresponding texture images as well as the structural similarity among...

In this paper, a low-complexity algorithm is proposed to reduce the complexity of depth map compression in the high-efficiency video coding (HEVC)-based 3D video coding (3D-HEVC). Since the depth map and the corresponding texture video represent the same scene in a 3D video, there is a high correlation among the coding information from depth map and texture video. An experimental analysis is pe...

H.264/AVC video coding standard performs motion estimation using various motion partition sizes. It has been shown to improve the coding gain. However, video coding using blocks bigger than 16×16 pixels can provide a substantial coding gain compared to H.264/AVC, especially when applied to high definition video sequences. Even if coding efficiency is improved, the complexity of motion estimatio...

The latest video coding standard High Efficiency Video Coding (HEVC) [1] provides 50% improvement in coding efficiency compared to H.264/AVC, to meet the rising demand for video streaming, better video quality and higher resolutions. The coding gain is achieved using more complex tools such as larger and variable-size coding units (CU) in a hierarchical structure, larger transforms and longer i...
