We describe a new method for 2D fiducial tracking. We use region adjacency information together with angles between regions to encode IDs inside fiducials, whereas previous research by Kaltenbrunner and Bencina utilize region adjacency tree. Our method supports a wide ID range and is fast enough to accommodate real-time video. It is also very robust against false positive detection.

Humans focus attention on different face regions when recognizing face attributes. Most existing face attribute classification methods use the whole image as input. Moreover, some of these methods rely on fiducial landmarks to provide defined face parts. In this paper, we propose a cascade network that simultaneously learns to localize face regions specific to attributes and performs attribute ...

An equivalence relation E on a standard Borel space is hyperfinite if E is the increasing union of countably many Borel equivalence relations En where all En-equivalence classs are finite. In this article we establish the following theorem: if a countable abelian group acts on a standard Borel space in a Borel manner then the orbit equivalence relation is hyperfinite. The proof uses constructio...
