Image Gathering and Reconstruction
This chapter develops the mathematical model that combines image gathering and display with digital processing and interpolation. The model (Fig. 2.1) contains all the elements that are required to account for the continuous transfer functions of optical apertures and the discrete transfer functions of digital processing. Section 2.1 addresses image gathering and display, which represents traditional telephotography and television, and Section 2.2 adds digital processing and interpolation to these input and output transformations.
