Abstract

. We argue that actions represent the basic seed of intelligence underlying perception of the environment, and the representations encoding actions should be the starting point upon which further studies of cognition are built. In this paper we make a first effort in characterizing these action representations. In particular, from the study of simple actions related to 3D rigid motion interpretation, we deduce a number of principles for the possible computations responsible for the interpretation of space-time geometry. Using these principles, we then discuss possible avenues on how to proceed in analyzing the representations of more complex human actions. 1 Introduction and Motivation During the late eighties, with the emergence of active vision, it was realized that vision should not be studied in a vacuum but in conjunction with action. Adopting a purposive viewpoint makes visual computations easier by placing them in the context of larger processes that accomplish tasks....
