Reducing the Computational Complexity of a Map Post-Processing Algorithm for Video Sequences
Maximum a posteriori (MAP) filtering using the HuberMarkov random field (HMRF) image model has been shown in the past to be an effective method of reducing compression artifacts i...

Best of both: a hybridized centroid-medoid clustering heuristic
Although each iteration of the popular kMeans clustering heuristic scales well to larger problem sizes, it often requires an unacceptably-high number of iterations to converge to ...

Separate Compositional Analysis of Class-Based Object-Oriented Languages
Abstract. We present a separate compositional analysis for objectoriented languages. We show how a generic static analysis of a context that uses an object can be split into two se...
