Motion-Sketch Based Video Retrieval Using a Trellis Levenshtein Distance
We present a fast technique for retrieving video clips using free-hand sketched queries. Visual keypoints within each video are detected and tracked to form short trajectories, wh...

The Differential Ant-Stigmergy Algorithm applied to dynamic optimization problems
— Many real-world problems are dynamic, requiring an optimization algorithm which is able to continuously track a changing optimum over time. In this paper, we present a stigmerg...

Collaborative Schema Construction using Regular Sequence Types
In this paper we describe an approach to build XML schemas in a collaborative way. The approach is based on computing intersection between sequences of type terms built over const...
