Performance comparison of arithmetic and Huffman coder applied to EZW codec
Reena Singh, Vinay Kumar Srivastava · 2012
In this paper, a performance comparison of an embedded zero tree wavelet (EZW) based codec is done on the basis of Huffman and arithmetic coding. The sub-band decomposition coefficients are coded into multilayer bit stream and then it is entropy coded using Huffman and arithmetic code. The comparison results shows that the arithmetic coded bit stream results in improved bit rate than Huffman coding at the same threshold.
