Abstract: An image processor device includes a computer processor unit (CPU), at least one memory connected to the CPU, and device for transferring images to the CPU. The memory contains an image-processing program for processing images showing at least one person. The program performs the following operations: detecting at least a face in each image and extracting therefrom a biometric template of the face; for each image, storing in a database an image reference, the biometric template, and if possible context information for the image; comparing the biometric templates corresponding to different image references with one another and associating together the image references for which the comparison has a similarity score greater than a predetermined threshold; and searching for context information corresponding to at least one of the references of the associated images, and if there is corresponding context information, establishing a link between the associated images.

Abstract: Systems and methods for providing for efficient switchover for a client in a storage network between the use of one or more a primary storage resources to one or more disaster recovery (DR) resources are provided herein. Embodiments may implement synchronization between such resources on a data plane and a control plane to allow for a transition between resources to be implemented in a manner that is minimally disruptive to a client. Moreover, embodiments may provide for processing resources which allow for switching a client between a primary storage resource to a secondary storage resource with minimal administrative interaction.

Abstract: Synchronous local and cross-site switchover and switchback operations of a node in a disaster recovery (DR) group are described. In one embodiment, during switchover, a takeover node receives a failover request and responsively identifies a first partner node in a first cluster and a second partner node in a second cluster. The first partner node and the takeover node form a first high-availability (HA) group and the second partner node and a third partner node in the second cluster form a second HA group. The first and second HA groups form the DR group and share a storage fabric. The takeover node synchronously restores client access requests associated with a failed partner node at the takeover node.
