Download or read book High Efficiency Video Coding (HEVC) written by Vivienne Sze and published by Springer. This book was released on 2014-08-23 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides developers, engineers, researchers and students with detailed knowledge about the High Efficiency Video Coding (HEVC) standard. HEVC is the successor to the widely successful H.264/AVC video compression standard, and it provides around twice as much compression as H.264/AVC for the same level of quality. The applications for HEVC will not only cover the space of the well-known current uses and capabilities of digital video – they will also include the deployment of new services and the delivery of enhanced video quality, such as ultra-high-definition television (UHDTV) and video with higher dynamic range, wider range of representable color, and greater representation precision than what is typically found today. HEVC is the next major generation of video coding design – a flexible, reliable and robust solution that will support the next decade of video applications and ease the burden of video on world-wide network traffic. This book provides a detailed explanation of the various parts of the standard, insight into how it was developed, and in-depth discussion of algorithms and architectures for its implementation.

Download or read book Advanced Motion Compensation for Video Coding Based on Delaunay Meshes written by Martina Eckert and published by LAP Lambert Academic Publishing. This book was released on 2012 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the investigative work on an advanced video coder based on the structure of a classical predictive coding scheme, substituting two basic components: a) motion prediction is made with triangle meshes instead of blocks; b) transform coding is realized with discrete wavelet transform instead of DCT. These parts have been investigated separately by many scientists but never before in combination. Within this framework, the author investigated the individual processing of arbitrarily shaped regions with the aim of preferential coding. Here, different types of regions were considered: pre-segmented objects, and regions created with help of the triangle mesh. The mesh regions extract skin-colored areas, or those with a high prediction error to code them with preference in order to achieve locally higher subjective qualities. Results show, that the combination of mesh-based motion prediction and wavelet transform yields better subjective and objective image coding quality than either of them in combination with a block-based technique.

Available in PDF, EPUB and Kindle. Book excerpt: In order for wireless devices to function, the signals must be coded in standard ways so that the sender and the receiver can communicate. This area of video source coding is one of the key challenges in the worldwide push to deliver full video communications over wireless devices. Video Coding for Mobile Communications reviews current progress in this field and looks at how to solve some of the most important technology issues in the months and years ahead. The vision of being able to communicate from anywhere, at any time, and with any type of information is on its way to becoming reality. This natural convergence of mobile communications and multimedia is a field that is expected to achieve unprecedented growth and commercial success. Current wireless communication devices support a number of basic multimedia services (voice, messages, basic internet access), but have coding problems that need to be solved before "real-time" mobile video communication can be achieved.

Download or read book New Methods for Motion Estimation with Applications to Low Complexity Video Compression written by Zhen Li and published by . This book was released on 2005 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: The goal in video compression is to remove the redundancy in a video sequence while preserving its fidelity. Motion estimation can significantly improve video coding efficiency by reducing temporal redundancy. In this thesis we focus on new methods for motion estimation with applications in low complexity video compression. In this thesis we study the performance of low complexity video coding. Theoretical rate-distortion performance is derived and evaluated for both low complexity video coding and conventional motion-compensated prediction (MCP) based video coding. Based on our analysis of sub-pixel and multi-reference motion search methods used to improve low complexity video coding efficiency, we propose a new refined side motion estimation method to better extract motion information at the video decoder. Motion side estimation methods in general assume a motion model in a video sequence and use computationally intensive motion search. In this thesis we propose a novel side information estimation method based on universal prediction. Our method does not assume an underlying motion model. Instead, it makes predictions based on its observation of the past video information. The experimental results show that this new method can significantly reduce the computational complexity while achieving comparable performance for many video sequences. Lossy image and video compression is often accompanied by annoying artifacts. In this thesis we present a transform domain Markov Random Field model to address the artifact reduction. We present two methods, which we denote as TD-MRF and TSD-MRF, based on this model. We show by objective and subjective comparisons that transform domain post processing methods can substantially reduce the computational complexity compared with conventional spatial domain method and still achieve significant artifact reduction.

Download or read book Advanced Motion Modeling for 3D Video Coding written by Nikola Bož̆inović and published by . This book was released on 2006 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Driven by new multimedia applications and the growing demand for more flexible and efficient transmission of video, a new approach to video coding has been recently proposed as an alternative to classical hybrid schemes. Instead of sequential frame-based predictive processing, the new approach is based on spatio-temporal 3D transforms, open-loop non-predictive processing, and embedded quantization and coding. This thesis investigates motion modeling for this new coding environment, as well as the impact of such modeling on both coder design and performance. The first aspect of this thesis deals with video coding based on 3D discrete cosine transform (DCT). We analyze 3D DCT spectrum properties of a globally translating image and show how to use its characteristic footprint for fast and efficient video coding. Previous approaches to 3D DCT video coding have lead to rather modest compression gains due to a limited use of motion characteristics in the transform domain. We develop a coefficient scanning order that adapts to motion, unlike the fixed zig-zag scanning of JPEG. We combine this adaptive scanning with a new 3D quantization model to design a low-complexity 3D DCT video coder. The new coder consistently outperforms MPEG-2 both subjectively and objectively (by more than 1.5 dB) at about 25% reduced complexity, while approaching the performance of MPEG-4 (within 0.8 dB) at less than half computational complexity. The second aspect of this thesis involves the role of motion in emerging video coders based on 3D discrete wavelet transform (DWT) and motion-compensated temporal filtering (MCTF). Motion invertibility, central to the optimality of lifted MCTF implementation, is first investigated. We introduce a metric for invertibility error between two motion fields. We develop advanced motion inversion methods and demonstrate their effectiveness in improving the update lifting step. Experimental results confirm that a better motion inversion, quantified by lower invertibility error, leads to an increase in coding gain up to 0.5 dB over simpler inversion techniques. We propose a new method for occlusion-aware modeling and estimation of motion fields and use it to create an adaptive 3D DWT coding structure. Implicit modeling of occluded/uncovered areas, combined with the use of longer wavelet kernels, improves both the prediction and update lifting steps and results in the overall compression gain of up to 1 dB over a non-adaptive coder.

Available in PDF, EPUB and Kindle. Book excerpt: This book describes recent innovations in 3D media and technologies, with coverage of 3D media capturing, processing, encoding, and adaptation, networking aspects for 3D Media, and quality of user experience (QoE). The contributions are based on the results of the FP7 European Project ROMEO, which focuses on new methods for the compression and delivery of 3D multi-view video and spatial audio, as well as the optimization of networking and compression jointly across the future Internet. The delivery of 3D media to individual users remains a highly challenging problem due to the large amount of data involved, diverse network characteristics and user terminal requirements, as well as the user’s context such as their preferences and location. As the number of visual views increases, current systems will struggle to meet the demanding requirements in terms of delivery of consistent video quality to fixed and mobile users. ROMEO will present hybrid networking solutions that combine the DVB-T2 and DVB-NGH broadcast access network technologies together with a QoE aware Peer-to-Peer (P2P) distribution system that operates over wired and wireless links. Live streaming 3D media needs to be received by collaborating users at the same time or with imperceptible delay to enable them to watch together while exchanging comments as if they were all in the same location. This book is the last of a series of three annual volumes devoted to the latest results of the FP7 European Project ROMEO. The present volume provides state-of-the-art information on 3D multi-view video, spatial audio networking protocols for 3D media, P2P 3D media streaming, and 3D Media delivery across heterogeneous wireless networks among other topics. Graduate students and professionals in electrical engineering and computer science with an interest in 3D Future Internet Media will find this volume to be essential reading.
