Tracking Objects Using Wavelets and Shearlets


Edge detection determines the boundary of objects in an image. In some applications a sequence of images records a 2D representation of a scene changing over time, giving 3D data. New 3D edge detectors, particularly ones we developed using shearlets and hybrid shearlet-Canny algorithms, identify edges of complicated objects much more reliably than standard approaches, especially under high noise conditions. We also use edge information to derive position and velocity via an optimization algorithm.

This is joint work with David Schug and Glenn Easley.
