Adaptive View-Based Appearance Models

We present a method for online rigid object tracking using an adaptive view-based appearance model. When the object’s pose trajectory crosses itself, our tracker has bounded drift and can track objects undergoing large motion for long periods of time. Our tracker registers each incoming frame against the views of the appearance model using a twoframe registration algorithm. Using a linear Gauss...

Active blobs: region-based, deformable appearance models

A region-based approach to nonrigid motion tracking is described. Shape is defined in terms of a deformable triangular mesh that captures object shape plus a color texture map that captures object appearance. Photometric variations are also modeled. Nonrigid shape registration and motion tracking are achieved by posing the problem as an energy-based, robust minimization procedure. The approach ...
