Abstract

The visual looming effect has been shown to be very important when action is taking place. In this paper we take a quantitative approach to visual looming. We define looming mathematically, show geometrical properties of objects that produce the same value of looming, and summarize results on measuring looming including how a multiresolution logarithmic retina simplifies this measurement.
