Abstract

Given a number of cluttered pictures containing cars (or faces, or shoes) can a model of `car' be learnt without human supervision? I will present a solution to this problem. It is based on learning probabilistic object models composed of `parts' and `shape'. Learning happens in two phases: at first a large number of promising candidate features are selected; then a shape density and the model features are estimated simultaneously. I will present a number of experiments demonstrating excellent detection and generalization performance. ------- Joint work with Markus Weber, Max Welling and Wolfgang Einhauser
