Two fast illumination invariant image retrieval methods for scenes comprising textured objects with variable illumination are introduced. Both methods are based on texture gradien...
Abstract—With the wide support for serialization in objectoriented programming languages, persistent objects have become common place. Retrieving previously “persisted” objec...

This paper presents a technique to enable deformable regions to be matched using image databases based on the information provided by the differential invariants of local histogram...
This paper introduces a new texture analysis scheme, which is invariant to local geometric and radiometric changes. The proposed methodology relies on the topographic map of images...
Abstract. For shapes represented as closed planar contours, we introduce a class of functionals that are invariant with respect to the Euclidean and similarity group, obtained by p...
