ABSTRACT:
Transform data is partitioned to more efficiently process requests in a server to transfer source data to a client. The transform data, generated from source data, comprises spatially related coefficients such that a block of coefficients permits reconstruction of identifiable portions of the source data. The transform data is partitioned into a plurality of partitions of coefficients. Each partition consists of coefficients for reconstruction of an identifiable portion of the source data. The client generates a request for one or more partitions of coefficients. The client request is sent to the server. The server extracts the partitions of coefficients set forth in the request, and transfers the partitions of coefficients to the client. Techniques for partitioning of transform data to support lossy compression are disclosed.
