We present a multi-view three dimensional intelligent surveillance system. We use a multi-agent framework to identify the behaviors of individuals in the scene. Detection and interpretation are performed completely in 3D space. A moving train coach is monitored by eight fish-eye cameras. Segmentation masks extracted from the undistorted images are fed to a distributed 3D reconstruction algorithm producing an octree-based description of the volume at each frame. Voxel-based algorithms extract connected-regions and their descriptions from consecutive models. The set of regions is mapped to a set of agents. We achieve dynamically consistent high-level interpretations by combining probabilistic models of human behaviors and intelligent reasoning.
Resumen-Yard Allocation Problem (YAP) is a frequently problem observed in port logistic operations, and consists in a temporary assignment of cargo containers, both export and import, to blocks storage located in the operation zone of seaports. The principal objective of YAP resolution is to improve the operations efficiency both terminal port as shipping companies that use the seaport, which allow to decrease operational cost and increasing the global efficiency. In this sense, this work proposes to solve the YAP using a constructive algorithm based in restrictions for each container. Official data of Arica Seaport -Chile were used for defining an experimental scenario, which allowed obtaining promising results. The constructive algorithm represents a novel approach because allows getting solutions in a simple and fast way, while satisfying the existing set of constrains associated with the general operation model.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
