Good public-key infrastructures (PKIs) are essential to make electronic commerce secure. Quite recently, certificate verification trees (CVTs) have been introduced as a tool for im...
We outline a method for measuring in an efficient way an overall degree of similarity between different leaf-labelled trees. In particular, we consider rooted trees, either unorde...
This paper discusses the use of Binary Partition Trees (BPTs) for object detection. BPTs are hierarchical region-based representations of images. They define a reduced set of regio...
Recent advances in GPU programmability and architecture have allowed for the generation of ray casted or ray traced images at interactive rates. How quickly these images can be ge...
Learning a tree substitution grammar is very challenging due to derivational ambiguity. Our recent approach used a Bayesian non-parametric model to induce good derivations from tr...
