A Kind of High Speed and High Quality Embedded Zerotree Coding Algorithm for Hardware Implementation
a kind of high speed and high quality embedded zerotree coding algorithm for hardware implementation was presented
significance map structure was simplified
and some redundance structure was reduced.Some useless zerotrees were minished and some isolation zeros not to be kept were cleared up so that efficiency of significance map coding rose.It improved image compression performance
reduced coding and decoding execution time.We designed the biorthogonal 9/7 wavelet basis based on lifting scheme so that it not only raised wavelet transform speed
but also ensured hardware implementation.The simulation experimentation showed that this method improved speed of wavelet transform and shortened time of coding and decoding.It raised image compression rate and improved quality of restructure image.
