A fixation and viewpoint measure for object-based gaze control.

摘要

Natural vision systems which are active benefit not only in terms of survival but also in the relative simplicity of their architecture and required computations. Three characteristics of animate systems which achieve such simplicity are, a) the ability to change viewpoint is equivalent to transforming internal models and allows acquisition of new information, b) control of position according to sensory feedback removes the necessity for measurement and calibration, c) processing resources are concentrated only in areas relevant to current perception. In this paper we present a gaze control fixation measure as part of a project to develop a multi-level, active, feedback control, robotic vision system situated in a dynamic environment, with the ultimate aim of investigating general cognitive processes in natural living systems. 1 Introduction This paper presents a cognitive model of a vision system based upon a view of control theory that has been proposed as a rationale for perception...
