Accurate measurement and identification of blood vessels could provide useful information to clinical diagnosis. A piecewise Gaussian model is proposed to describe the intensity distribution of vessel profile in this paper. The characteristic of central reflex is specially considered in the proposed model. The comparison with the single Gaussian model is performed, which shows that the piecewis...

A GIS multivariate model based on the Mahalanobis distance statistic is proposed to evaluate habitat suitability for the wolf Canis lupus in northern Spain. Results derived from the model show that wolves can potentially thrive in some habitats on the southern and western side of the study area where conflicts with the human population are minimum. However, some other areas that have been recen...

This paper focuses on the problem of kernelizing an existing supervised Mahalanobis distance learner. The following features are included in the paper. Firstly, three popular learners, namely, “neighborhood component analysis”, “large margin nearest neighbors” and “discriminant neighborhood embedding”, which do not have kernel versions are kernelized in order to improve their classification per...
