High Compression coding techniques developments.
The JRC contribution
The Fundamental ideais to combine innovative wavelets and Fractal techniques, in order to use the most promising results of these two mathematical theory.
The developments at the JRC are:
- 1- Define the eingen wavelets associated with a specific image.
- 2- Compress the associated "image" using a block iterative scheme using eingen - wavelets.
- 3- Define the eingen operator for associated quantification.
- 4- Apply the advance lossless compression techniques for having the final result (LZW, Huffman, arithmetic coding ...). During the previous step, the Fractal dimension and associated directory are computed, Thus adaptive wavelet techniques can be defined for the reconstruction.
- 5- The reconstruction process is performed in the reverse order except the quantification.
- 6- During the reconstruction process, Fractal and eingen wavelets dictionary are updated.
- 7- Finally the original image has been reconstructed but enlargement and zooming are now available in the same way as the Fractals.
In short, the advanced original method could be described as : an adaptive Fractal and wavelet block iterative technique which is derived from the diffraction coherence light theory which has been discovered and patented by the JRC.
