A case study of image retrieval on lung cancer chest x-ray pictures.
(Conference)This paper presents a case study of an image retrieval system based on a notion of similarity between images in a multimedia database and where a user request can be an image file or a keyword. The CBIR (Content Based Image ... -
CCA: a calculus of context-aware ambients.
(Conference)We present a process calculus, CCA, for the modelling and verification of mobile systems that are context-aware. This process calculus is built upon the calculus of mobile ambients and introduces new constructs to enable ... -
Challenges and Open Questions in Soft Consensus Models
(Conference)In group decision making problems, given the importance of obtaining an accepted solution by the whole group, the consensus has attained a great attention and it is virtually a major goal of these problems. Consensus, as ... -
