In this chapter, we discuss the uses of the term “multimedia” since people may have quite different, even opposing, viewpoints on what this means. This textbook is aimed at computer science or engineering students, and consequently a more applica

In this chapter, color and color spaces are introduced; without excellent color, images and video would look unacceptable. But how is this accomplished in the real world, light bounces off surfaces and the resulting spectrum enter the eye. Retinal se

The video coding standards H.264, H.265, and H.266 were jointly developed by ISO/IEC MPEG and ITU-T VCEG (Video Coding Experts Group). The main objective of H.264 (aka. AVC) and H.265 (aka. HEVC) was to improve the coding efficiency so as to deal wit

Recent years have seen an explosion in the availability of digital images. In this chapter, we examine some current image compression standards and demonstrate how techniques presented in Chaps. 7 and 8 are applied in practice. We first describe how

A video can be viewed as a sequence of images stacked in the temporal dimension. Since the frame rate of the video is often relatively high, the contents of consecutive frames are usually similar. In other words, video has temporal redundancy. All di

In this chapter, we consider the set of tools for audio compression applicable to general audio, such as music, as opposed to specifically speech compression developed under the aegis of the Motion Picture Experts Group, MPEG. Surprisingly, this subj

In this chapter we examine compression algorithms such that recovered input data cannot be exactly reconstructed from compressed version. This termed “loss”. What we have, then, is a tradeoff between efficient compression versus a less accurate v

Imagine a world in which the physical objects surrounding us could be constructed or destructed on a whim, tinkered and adjusted to fit the demands of the user. Such a world may never exist in the physical domain, but the worlds of augmented reality
