We present an approach for measuring similarity between visual entities (images or videos) based on matching internal self-similarities. What is correlated across images (or acros...
— We consider a distributed system modeled as a possibly large network of automata. Planning in this system consists in selecting and organizing actions in order to reach a goal ...
When a database is defined as views over autonomous sources, inconsistencies with respect to global integrity constraints are to be expected. This paper investigates the possibili...
