Lifting Scheme Combined with SPIHT Color Image Compression Algorithm

摘要

The embedded zero tree wavelet coding algorithm in wavelet transform domain is the efficient image compression coding algorithm, the wavelet transform coefficients according to their order of importance to, realize the progressive image coding, based on aggregation and S transform and MRCT transform in the lossless compression algorithm for image, through the simulation experiment, the JP2 respectively, RAR, ZIP, PNG, TGA, PCX, TIF lossless compression results improved an average of 2%, 15%, 51%, 51%, 34%, 52%, 31%.
