Figure 1.11 Relationship between images, geometry, and photometry, as well as a taxonomy of the topics cov-
ered in this book. Topics are roughly positioned along the left–right axis depending on whether they are more
closely related to image-based (left), geometry-based (middle) or appearance-based (right) representations, and
on the vertical axis by increasing level of abstraction. The whole figure should be taken with a large grain of salt,
as there are many additional subtle connections between topics not illustrated here.
