In the article we present the process of scene model fusion. It consists of several iterations performed separately for each viewpoint. In the approach we find a weak subgraph isomorphism from a graph of a new observation to a model graph. We combine a modified Ullman algorithm for subgraph matching with Procrustes methods of 3D shape analysis. Such solutions make it possible to quickly and acc...

The statistical analysis of covariance matrix data is considered, and in particular methodology is discussed which takes into account the non-Euclidean nature of the space of positive semi-definite symmetric matrices. The main motivation for the work is the analysis of diffusion tensors in medical image analysis. The primary focus is on estimation of a mean covariance matrix, and in particular ...

Feeding adaptation, social behaviour, and interspecific interactions related to sexual dimorphism and allometric growth are particularly challenging to be investigated in the high sexual monomorphic Delphinidae. We used geometric morphometrics to extensively explore sexual dimorphism and ontogenetic allometry of different projections of the skull and the mandible of the bottlenose dolphin Tursi...
