As new displays and cameras offer enhanced color capabilities there is a need to extend the
precision of digital content. High Dynamic Range (HDR) imaging encodes images and video with
higher than normal 8 bit-per-color-channel precision enabling representation of the complete
color gamut and the full visible range of luminance.However to realize transition from the
traditional toHDRimaging it is necessary to develop imaging algorithms that work with the
high-precision data. Tomake such algorithms effective and feasible in practice it is necessary
to take advantage of the limitations of the human visual system by aligning the data
shortcomings to those of the human eye thus limiting storage and processing precision.
Therefore human visual perception is the key component of the solutions we discuss in this
book.This book presents a complete pipeline forHDR image and video processing fromacquisition
through compression and quality evaluation to display. At the HDR image and video acquisition
stage specialized HDR sensors or multi-exposure techniques suitable for traditional cameras are
discussed. Then we present a practical solution for pixel values calibration in terms of
photometric or radiometric quantities which are required in some technically oriented
applications. Also we cover the problem of efficient image and video compression and encoding
either for storage or transmission purposes including the aspect of backward compatibility
with existing formats. Finally we review existing HDR display technologies and the associated
problems of image contrast and brightness adjustment. For this purpose tone mapping is employed
to accommodate HDR content to LDR devices. Conversely the so-called inverse tone mapping is
required to upgrade LDR content for displaying on HDR devices. We overview HDR-enabled image
and video quality metrics which are needed to verify algorithms at all stages of the pipeline.
Additionally we cover successful examples of the HDR technology applications in particular
in computer graphics and computer vision.The goal of this book is to present all discussed
components of the HDR pipeline with the main focus on video. For some pipeline stages HDR video
solutions are either not well established or do not exist at all in which case we describe
techniques for single HDR images. In such cases we attempt to select the techniques which can
be extended into temporal domain. Whenever needed relevant background information on human
perception is given which enables better understanding of the design choices behind the
discussed algorithms and HDR equipment.Table of Contents: Introduction Representation of an
