Genetic algorithm based on discrete wavelet transformation for fractal image compression
The DWT method can save seven eighths MSE computations. Two DWT coefficients have the information of edge and brightness variation. Two DWT coefficients are used to find the optimal Dihedral transformation. We embed the DWT into the GA to speedup the fractal encoder further. The shorter chromosome is obtained to speedup the GA evolution.
