The Art and Science of HDR Imaging (Hardcover)

Rendering High Dynamic Range (HDR) scenes on media with limited dynamic range began in the Renaissance whereby painters, then photographers, learned to use low-range spatial techniques to synthesize appearances, rather than to reproduce accurately the light from scenes. The Art and Science of HDR Imaging presents a unique scientific HDR approach derived from artists’ understanding of painting, emphasizing spatial information in electronic imaging.

Human visual appearance and reproduction rendition of the HDR world requires spatial-image processing to overcome the veiling glare limits of optical imaging, in eyes and in cameras. Illustrated in full colour throughout, including examples of fine-art paintings, HDR photography, and multiple exposure scenes; this book uses techniques to study the HDR properties of entire scenes, and measures the range of light of scenes and the range that cameras capture. It describes how electronic image processing has been used to render HDR scenes since 1967, and examines the great variety of HDR algorithms used today. Showing how spatial processes can mimic vision, and render scenes as artists do, the book also:

• Gives the history of HDR from artists' spatial techniques to scientific image processing
• Measures and describes the limits of HDR scenes, HDR camera images, and the range of HDR appearances
• Offers a unique review of the entire family of Retinex image processing algorithms
• Describes the considerable overlap of HDR and Color Constancy: two sides of the same coin
• Explains the advantages of algorithms that replicate human vision in the processing of HDR scenes
• Provides extensive data to test algorithms and models of vision on an accompanying website

在有限動態範圍的媒體上呈現高動態範圍（HDR）場景的渲染始於文藝復興時期，當時畫家和攝影師學會使用低範圍的空間技巧來合成外觀，而不是準確地再現場景中的光線。《HDR影像的藝術與科學》提出了一種獨特的科學HDR方法，該方法源於藝術家對繪畫的理解，強調電子影像中的空間信息。

人類視覺外觀和HDR世界的再現需要空間圖像處理來克服光學成像中的遮蔽光限制，包括眼睛和相機。本書全彩插圖，包括精美藝術作品、HDR攝影和多重曝光場景的示例；使用技術來研究整個場景的HDR特性，並測量場景的光線範圍和相機捕捉的範圍。它描述了自1967年以來電子影像處理如何用於渲染HDR場景，並檢查了當今使用的各種HDR算法。本書還展示了空間處理如何模仿視覺，並像藝術家一樣呈現場景，同時還：

- 提供了從藝術家的空間技巧到科學影像處理的HDR歷史
- 測量並描述了HDR場景、HDR相機圖像和HDR外觀的限制
- 提供了對Retinex影像處理算法家族的獨特評論
- 描述了HDR和色彩恆常性之間的重疊：同一個硬幣的兩面
- 解釋了在處理HDR場景時複製人類視覺的算法的優勢
- 在附帶網站www.wiley.com/go/mccannhdr上提供了廣泛的數據來測試視覺算法和模型。
