Artículo
Acceso abiertoThe appearance of the city is strongly linked to many aspects such as climate, culture and sociological background. In cities with a prevalence of clear skies, one of the determining aspects is the climatic condition, which ... -
A discrete labelling approach to attributed graph matching using SIFT features
(2010)
Texto en actas de congreso
Acceso abiertoLocal invariant feature extraction methods are widely used for image-features matching. There exist a number of approaches aimed at the refinement of the matches between image-features. It is a common strategy among these ... -
A new otolith image contour descriptor based on partial reflection
(2010-12)
Artículo
Acceso restringido por política de la editorialIn this paper we propose a new contour descriptor for reconstructing fish otolith contours that uses half the number of coefficients needed by the classical elliptical Fourier descriptors (EFDs) for the same accuracy. ... -
