A novel image segmentation algorithm was developed to allow the automatic segmentation of both normal and abnormal anatomy from medical images. The new algorithm is a form of spatially varying statistical classification, in which an explicit anatomical template is used to moderate the segmentation obtained by statistical classification. The algorithm consists of an iterated sequence of spatiall...

Online communities provide a social sphere for people to share information and knowledge. While information sharing is becoming a ubiquitous online phenomenon, how to ensure information quality or induce quality content, however, remains a challenge due to the anonymity of commentators. This paper introduces moderation into reputation systems. We show that moderation directly impacts strategic ...

This paper introduces regular extrapolation, a technique that provides descriptions of systems or system aspects a posteriori in a largely automatic way. The descriptions come in the form of models which offer the possibility of mechanically producing system tests, grading test suites and monitoring running systems. Regular extrapolation builds models from observations via techniques from machi...
