Wenjuan Wang · Computer Knowledge and Technology · 2009
One of the improved algorithms is recommended according to the characteristic of wavelet package analysis, which attempts to combine the fractal coding theory and the wavelet package transformation to compress image. In detail, the image is decomposed by the wavelet package f irstly, then the high frequency part is compressed by traditional wavelet transformation, and the low frequency part is compressed through fractal coding technique. The above-mentioned methods encoding speed of 20 times, while the reconstructed images have better Subjective f idelity compared with those got through basic fractal coding methods. Experiments demonstrate the eff iciency of this method.
