1. A method for handling image data, the method comprising:

  • decomposing the image data into a plurality of data sets using lossless wavelet decomposition;

    tessellating at least one decomposed set of the plurality of data sets into a plurality of blocks;

    compressing each tessellated block of the plurality of blocks using lossless compression; and

    compiling a data stream comprising the compressed plurality of blocks arranged sequentially in a desired order based upon the decomposition and tessellation.
