A general strategy for decomposing topological invariants of spatial databases and an application
Topological invariants of spatial databases (i.e., finite structures that capture the topological properties of the database) are receiving increasing attention since they can act...

Extension of Moment Features' Invariance to Blur
Moment invariants are features calculated on an image, which do not change their values after a transformation of the image. This paper focuses on the so called combined invariants...

Recognizing 3D Objects Using Photometric Invariant
In this paper we describe a new e cient algorithm for recognizing 3D objects by combining photometric and geometric invariants. Some photometric properties are derived, that are i...

Optical Tracking Using Projective Invariant Marker Pattern Properties
In this paper, we describe a new optical tracker algorithm for the tracking of interaction devices in virtual and augmented reality. The tracker uses invariant properties of marke...
