Abstract

Data representing, for instance, an image is lossily encoded, and a residual of the data is losslessly encoded. The lossily encoded data and the losslessly encoded residual provide a losslessly compressed data representation of the original data. The losslessly compressed data is then organized and stored on a storage system according to one or more criteria selected for the particular losslessly encoded data to be organized. This enables the efficient retrieval and processing of the compressed data, including retrieval of portions of the compressed data.
