Abstract

The goal of this work is to provide information for the automatic control of an active camera. One way to achieve this is to run a set of saliency detectors in the scene which is tuned to a specific class of objects. As opposed to this, we propose a formal definition for what we mean for salient motion by means of the concept of stationarity of stochastic processes. We propose a hierarchy of generative models for salient and nuisance motion, along with recursive learning procedures for on-line processing. By doing so, we turn the problem of detecting salient motion into the problem of model change detection, which we solve optimally online using the sequential generalized likelihood ratio test. Our system is designed for realtime applications, and is able to detect salient motion even in severely cluttered scenes.
