3D Object Modeling and Recognition Using Affine-Invariant Patches and Multi-View Spatial Constraints
14 years 9 months ago
: This paper presents a novel representation for three-dimensional objects in terms of affine-invariant image patches and their spatial relationships. Multi-view constraints associ...

The Rayleigh quotient of a bent function is an invariant under the action of the orthogonal group, and it measures the distance of the function to its dual. An efficient algorithm ...

This paper presents an approach for content-based image retrieval via isotropic and anisotropic mappings. Isotropic mappings are defined to be mappings invariant to the action of t...

We use group theory to construct infinite families of maps on surfaces which are invariant under Wilson's map operations of order 3 but not under the operations of order 2, s...

For shapes represented as closed planar contours, we introduce a class of functionals which are invariant with respect to the Euclidean group and which are obtained by performing i...
