ISPIHT-Improved SPIHT: A Simplified and Efficient Subband Coding Scheme
Yumnam Kirani Singh · 2007
Proposed here is a new subband coding scheme entitled ISPIHT (Improved SPIHT). It is simpler in its coding approach yet it is more efficient in time and memory keeping the performance of SPIHT preserved. It requires less no of compression operations during the coding. The memory requirement for ISPIHT is about two times less than SPIHT
