Algorithmic modifications to SPIHT
(IEEE, 2001) Bayazıt, Uluğ; Pearlman, William A.
This paper proposes several low complexity algorithmic modifications to the SPIHT (Set Partitioning in Hierarchical Trees) image coding method of [3] The modifications exploit universal traits common to the real world images Approximately 1-2 % compression gain (bit rate reduction for a given mean squared error) has been obtained for the images in our test suite by incorporating all Of the Proposed modifications into SPIHT.
