Chapter 11. Multiple Scale Analysis.
11.1. INTRODUCTION.
In previous chapters it has been shown how it is possible to derive a great deal of high fidelity data
from images by spatially and temporally interactive processing based on an interpretation of human
vision. One fact which must, however, be acknowledged, is that the incoming information content in
a scene, as imaged by any optics and sensed by any sampling system, must be dependent on the
distance of the scene detail from the imaging optics, the magnifying power of the optics (i.e. its focal
length) and/or the physical size of the sampling cells in the sensing system. Consider for a moment
what appears to happen with human vision. We are provided with an essentially fixed focal length
imaging optics (and therefore a fixed magnification of the incoming image on the retina). There is
thus a strict minimum size of detail, defined by the physical imaging properties and the sampling
