1 Introduction

This chapter is concerned with the sampled representation of time-varying imagery, often referred to as video. Time-varying imagery must be sampled in at least one dimension for the purposes of transmission, storage, processing or display. Examples are one-dimensional temporal sampling in motion-picture film, two-dimensional vertical-temporal scanning in the case of analog television, ...
