In the last few years, with the increasing popularity of cloud computing and the availability of
mobile smart devices as well as ubiquitous network connections, more and more users are …

This book explores the methods needed for creating and manipulating HDR content. HDR is
a step change from traditional imaging; more closely matching what we see with our eyes. In …

This paper proposes a novel framework of reversible data hiding in encrypted JPEG
bitstream. We first provide a JPEG encryption algorithm to encipher a JPEG image to a …

While most techniques of reversible data hiding in encrypted images (RDH-EI) are
developed for uncompressed images, this paper provides a separable reversible data …

Digital image capture, processing, storage, transmission, and display are now taken for
granted as part of the technology of modern everyday life. Digital image compression is one …

Many new DCT-like transforms have been proposed since the first edition of this book. For
example, the integer DCT that yields integer transform coefficients, the directional DCT to …

Controlling the quality of the images in JPEG is done by quantization tables. There are two
quantization tables–one for the luminance information and one for the chrominance …

Current image coding standards provide limited support for privacy and security features. An
exception is the JPSEC standard, which defines security extensions in JPEG 2000 …

In this lecture note, we describe high dynamic range (HDR) imaging systems. Such systems
are able to represent luminances of much larger brightness and, typically, a larger range of …

High-dynamic-range (HDR) images are widely regarded as the ideal format for digital
images due to their ability to accurately render a wider range of luminance values. Recently …
