商品描述

Communicating Pictures starts with a unique historical perspective of the role of images in communications and then builds on this to explain the applications and requirements of a modern video coding system. It draws on the author's extensive academic and professional experience of signal processing and video coding to deliver a text that is algorithmically rigorous, yet accessible, relevant to modern standards, and practical. It offers a thorough grounding in visual perception, and demonstrates how modern image and video compression methods can be designed in order to meet the rate-quality performance levels demanded by today's applications, networks and users. With this book you will learn:

  • Practical issues when implementing a codec, such as picture boundary extension and complexity reduction, with particular emphasis on efficient algorithms for transforms, motion estimators and error resilience
  • Conflicts between conventional video compression, based on variable length coding and spatiotemporal prediction, and the requirements for error resilient transmission
  • How to assess the quality of coded images and video content, both through subjective trials and by using perceptually optimised objective metrics
  • Features, operation and performance of the state-of-the-art High Efficiency Video Coding (HEVC) standard
  • Covers the basics of video communications and includes a strong grounding in how we perceive images and video, and how we can exploit redundancy to reduce bitrate and improve rate distortion performance
  • Gives deep insight into the pitfalls associated with the transmission of real-time video over networks (wireless and fixed)
  • Uses the state-of- the-art video coding standard (H.264/AVC) as a basis for algorithm development in the context of block based compression
  • Insight into future video coding standards such as the new ISO/ITU High Efficiency Video Coding (HEVC) initiative, which extends and generalizes the H.264/AVC approach

商品描述(中文翻譯)

《圖像傳輸》從獨特的歷史角度出發，探討圖像在通訊中的角色，並在此基礎上解釋現代視頻編碼系統的應用和要求。作者借鑒了自己在信號處理和視頻編碼方面的豐富學術和專業經驗，提供了一本算法嚴謹、易於理解、與現代標準相關且實用的教材。本書全面介紹了視覺感知，並展示了如何設計現代圖像和視頻壓縮方法，以滿足當今應用、網絡和用戶對速率和質量性能的要求。閱讀本書，您將學到以下內容：

- 實施編碼器時的實際問題，例如圖像邊界擴展和複雜度減少，特別強調有效算法的轉換、運動估計器和錯誤恢復。
- 傳統視頻壓縮（基於可變長度編碼和時空預測）與錯誤恢復傳輸要求之間的衝突。
- 如何通過主觀試驗和感知優化的客觀指標來評估編碼圖像和視頻內容的質量。
- 現代高效視頻編碼（HEVC）標準的特點、操作和性能。

本書還包括以下內容：

- 視頻通訊的基礎知識，並深入介紹我們如何感知圖像和視頻，以及如何利用冗餘來減少比特率並提高速率失真性能。
- 深入了解在網絡（無線和固定）上傳輸實時視頻時可能遇到的問題。
- 在基於塊的壓縮上下文中，以最先進的視頻編碼標準（H.264/AVC）為基礎進行算法開發。
- 深入了解未來的視頻編碼標準，如新的ISO/ITU高效視頻編碼（HEVC）倡議，該倡議擴展並推廣了H.264/AVC方法。
