5D Motion Subspaces for Planar Motion
In practice, rigid objects often move on a plane. The object then rotates around a fixed axis and translates in a plane orthogonal to this axis. For a concrete example, think of a...

Robust Head Motion Computation by Taking Advantage of Physical Properties
We present a new algorithm to compute the head motion between two views from the correspondences of five feature points (eye corners, mouth corners, and nose top), and zero or mor...

A Comparison of Shape Constrained Facial Feature Detectors
We consider the problem of robustly and accurately locating facial features. The relative positions of different feature points are represented using a statistical shape model. We...

The Distinctiveness, Detectability, and Robustness of Local Image Features
We introduce a new method that characterizes typical local image features (e.g., SIFT [9], phase feature [3]) in terms of their distinctiveness, detectability, and robustness to i...
