1. A method for processing data, the method comprising:

  • transforming the input data into a plurality of coefficients using a reversible wavelet filter, the reversible wavelet filter to apply a reversible wavelet transform to the input data;

    generating an embedded codestream in response to the plurality of coefficients;

    binary entropy coding the embedded codstream to produce the compressed data stream; and

    parsing the compressed data stream.
