Abstract

The SPIHT algorithm is a popular algorithm using wavelet techniques for image compression. In this paper, we present modifications to the algorithm by: 1) sending additional information to the decoder about the largest magnitudes in the frequency subbands; and 2) modifying selected coefficients in the high frequency subbands. The proposed modifications give an improvement to the algorithm performance without incurring much additional complexity.
