Partition lattice operators for extraction of semantic video objects

We conceive the problem of multiple semantic video object (SVO) extraction as an issue of designing operators on a complete lattice of partitions. In this paper, we propose a. framework based on accurate! spatial partition generation and application of optimal extraction operators on the generated partitions. Under the framework we introduce a spatio-temporal regional maximum likelihood operator for extraction purposes. Some theoretical properties of the operators are established. Experimental results show that our scheme is capable of successfully handling: multiple SVOs in a variety of scenarios.
