Abstract :
In this paper, six integer wavelet transforms are compared on marrow cell image energy distribution and their percentage of zero coefficients in every subband for higher performances of marrow cell image compression. A new method of quantization threshold is applied to EZW coding. The experiment results show that this approach can increase the number of zerotrees and improves marrow cell images compression
