| Abstract: | In this paper, wavelet based coding algorithm, Set
Partitioning in Hierarchical Trees (SPIHT), is considered for encoding and
decoding image data. SPIHT uses recursive set
partitioning procedure to sort subsets of wavelet coefficient by maximum
magnitude with respect to threshold. SPIHT is simple,
less complex and has very fast encoding and decoding, making it very
efficient in multimedia communication. Numerical results
obtained using MATLAB shows that output image has high value of
peak signal to noise ratio with good compression ratio
for low bit rate.
