  • It can code arbitrarily shaped object not only preserving visual texture information but also introducing no redundancy. Transforming arbitrarily shaped object will bring a little change because of the variety of sequence's length and subsample location, which was resolved by the method that arbitrarily shaped mask images were transformed through lazy wavelet and shape adaptive wavelet transform was resolved by lift-based wavelet of 9-7 filter banks. Finally arbitrarily shaped object texture was coded and compressed using the modified shape adaptive SPIHT. Comparison with origin algorithm shows the gain of 0.2 dB.
