摘要： 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.

摘要： Methods and systems of inserting image files into a container are described herein. One method includes overseeing a submission of images to containers, retrieving a job of inserting images into the container, and inserting images into the container by, for each of the plurality of images: (i) reading and analyzing source data including the image; (ii) opening the container, which includes records, where the image will be stored; (iii) determining whether the source data is valid to be entered into a record; (iv) responsive to a determination that the source of data is valid, preparing metadata; (v) writing the record into the container; and (vi) marking a status flag/mark of the record as being updated while writing the record into the container.

摘要： 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.

摘要： A system and method for storing data related to an image is disclosed. The method may include: unevenly dividing the image into polygonal image sections, each comprising pixels and each of the pixels having band(s) and a bit depth per band that is too high for displaying on a display screen; dividing the image into quads such that each quad has a boundary that contains at least a portion of one of the polygonal image sections; obtaining statistical data associated with the image, the statistical data being computed for each of the bands of each of the pixels within each of the polygonal image sections; storing, with respect to a reduced resolution dataset (R-Set) of the image, coordinates of bounds of at least one polygonal image section that intersects with a quad; organizing the image, the quads, and the polygonal image sections in a tree structure; and storing the statistical data, the pixel coordinates, and the tree structure.

摘要： A method and a computer system for WAMI discovery are provided. The method includes issuing a request to a WAMI collection service in one or more WAMI collection services to retrieve an entire collection tree metadata at said WAMI collection service; receiving a response from the WAMI collection service, the response comprising the entire collection tree metadata, the response being in a first format; and translating the response from the first format into KML format, wherein the translating includes mapping a one-to-one of WAMI collection tree nodes from the first format into KML nodes.

摘要： A method and system for storing data files are provided. The method includes receiving from a client computer system in communication with a server computer system, a first data file and a first data file virtualization policy; storing the first data file and the first data file virtualization policy on a storage device in communication with the server computer system; and deriving one or more second virtual data files using information from the first data file and the first data file virtualization policy, the one or more second virtual data files not being stored on the storage device. The method further includes generating a directory listing of the one or more second virtual data files such that the one or more second virtual data files appear to the client computer system as if the one or more second virtual data files is stored in the storage device.

摘要： A method and system of transmitting a plurality of wide-area surveillance area-of-interest video codestreams is described, First and second video codestreams are generated from a plurality of large format images that are captured sequentially in time. The first video codestream has a first plurality of areas-of-interest selected from the plurality of large format images and the second video codestream has a second plurality of areas-of-interest from the same plurality of large format images. The first video codestream is generated at a first frame rate and the second video codestream is generated at a second frame rate and the first and second video codestreams are combined to obtain a combined video codestream at third frame rate. The combined video codestream is then transmitted through a link to a demultiplexer that regenerates the first and second video codestreams.

摘要： Methods and systems of managing data files are described herein. One method includes updating a container file of data files having a container file metadata section and one or more empty records, each record of the one or more empty records having: (i) a data file section reserved for storing a data file, (ii) a file metadata section reserved for storing metadata about the data file, and (iii) a record metadata section including information about the record and having at least a record status mark indicating that the record is empty. The method includes setting the record status mark of the one or more empty records to being updated; writing one or more records containing the data file into the one or more empty records within the container file. After successfully writing the one or more records resetting the record status mark to valid.

摘要： A system and method of retrieving an area of interest of an image stored in a storage device. The method includes selecting the area of interest having user desired features, the stored image being divided into a plurality of polygonal image sections, each polygonal image section having substantially homogenous features, the image being further divided into a plurality of quads such that each quad has boundaries that contains at least a portion of a first polygonal image section and at least a portion of a second polygonal image section. The method further includes determining in which quad in the plurality of quads each pixel of the area of interest is located and determining for each quad, in which portion of the first polygonal image section or the second polygonal image section each pixel is located.
