Abstract We propose a robust methodology for 3D model-based markerless tracking of textured objects in monocular image sequences. The technique is based on mutual infor-mation maximization, a widely known criterion for multi-modal image registration, and employs an efficient multires-olution strategy in order to achieve robustness while keeping fast computational time, thus achieving near real-time per-formance for visual tracking of complex textured surfaces
