摘要：
A compression technique for image is proposed that is SPIHT algorithm based. Encoding of wavelet transformed quantized image is done using variants of Huffman coding. Comparisons are made among the binary un-coded SPIHT, SPIHT with Huffman coding, the proposed technique and its modified variant which show that the proposed techniques offer better PSNRs maintaining the same compression rates. But, the encoding time of the proposed techniques are slightly high.
