Compression reduces the number of bits required to represent a signal. The appropriate compression strategy is a function of the type of signal to be compressed. Here, we focus on images, which can be single component (e.g., gray scale) or multiple component (e.g., three-component color or highercomponent remote sensing data). Each component can be considered to be an “image” — a two-dimensional (2D) array of pixels, and this chapter reviews the fundamentals of image compression as a 2D signal with specific statistical characteristics. ...
