Abstract :
This paper proposes several low complexity algorithmic modifications to the SPIHT (set partitioning in hierarchical trees) image coding method of Said and Pearlman (1996). 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
