    Abstract: An image display system is disclosed that enables users to navigate very large digital images quickly and seamlessly. The system is optimized to transmit image data from a disk drive to a display at high data rates. The image data is stored on the disk drive in a file format optimized for high speed retrieval, display, and seamless navigation. The image display system can be cascaded for showing two or more contiguous images on multiple displays.

    Abstract: A method, implemented by a computer system, and a system of organizing data of a wide area motion imagery frame and a method and a system of retrieving objects that match a user defined AOI from an image in a WAMI frame in a WAMI collection are described. The method of organizing includes dividing, by the computer system, an image of a WAMI frame into a plurality of tiles, each tile in the plurality of tiles comprising a plurality of pixels and having a pixel width and a pixel height; storing, by the computer system, the plurality of tiles as objects in an OSD, each object having an object identifier (OID); collecting, by the computer system, object identifiers (OIDs) of the objects; and storing, by the computer system, the OIDs in the OSD.

    Abstract: A method and system for requesting information from a server are provided. The method may include sending, by a client to a server, an HTTP GET request to retrieve at least a portion of at least one derived data file, the at least one derived data file being dynamically generated by the server in response to the request using a data file virtualization policy and at least a portion of a data file. The data file virtualization policy and the data file may be stored in a storage accessible by the server, and the dynamic generation may comprise an aligned unbuffered direct read operation from the stored data file of a data size that is aligned to an integer multiple of the storage's block size. The at least the portion of the at least one derived data file may then be received by the client from the server.

    Abstract: This disclosure relates to WAMI discovery, specifically including: issuing a first request to a WAMI federated collection service (FCS) to retrieve WAMI collection metadata, the WAMI FCS being in communication with a WAMI collection service (CS), each WAMI CSs being in communication with a location where WAMI data is stored; receiving a response in a first format from the WAMI FCS; translating the received WAMI collection metadata from the first format into another format; issuing a second request to the WAMI FCS to access WAMI data in the other format; and retrieving in response to the second request, the WAMI data in the other format from the location that corresponds to a network link.

    Abstract: A system and method of selecting an area of interest from a plurality of images captured by a plurality of cameras are described. The method includes receiving a request for an area of interest from a plurality of images, the area of interest containing an object of interest selected by a user, the object of interest being captured in one or more images captured by one or more of the plurality of cameras, the plurality of cameras having overlapping field of views; determining a camera within the plurality of cameras that wholly contains the area of interest; transforming the physical location of the object of interest into a pixel position such that the area of interest being essentially centered around the pixel position corresponding to the physical location of the object of interest; and extracting the area of interest.

    Abstract: This disclosure provides a federated wide area motion imagery (WAMI) collection service (CS) by: receiving an alert from a WAMI alert-service (A) respectively associated with a WAMI CS regarding any updates to WAMI data served by the WAMI CS at the federated WAMI CS, the WAMI CS providing WAMI collection metadata; issuing a request to the WAMI A associated with the WAMI CS to read information on what is updated; receiving a response from the WAMI A at the federated WAMI CS, the response comprising tree nodes corresponding to WAMI collection metadata that are updated by the WAMI CS; issuing a subsequent request to the WAMI CS from the federated WAMI CS to retrieve the WAMI collection metadata from the WAMI CS corresponding to the collection tree nodes that are updated; receiving a response including the WAMI collection metadata from the WAMI CS; and storing the received WAMI collection metadata in cache of the federated WAMI CS of the system.
