Mehrotra, Abhishek and Srikanth, R and Ramakrishnan, AG (2004) A New Coding Scheme for 2-D and 3-D MR Images using Shape Adaptive Integer Wavelet Transform. In: International Conference on Intelligent Sensing and Information Processing., 4-7 January 2004, Chennai, India, pp. 67-72.
We propose a new Shape Adaptive Integer Wavelet Transform based progressive transmission coding scheme for 2-0 and 3-0 MRI. The scheme consists of (a) extraction of shape information (6) Shape Adaptive Integer Wavelet transform (c) Intrabrand Wavelet enoding arid (d) entropy coding. The proposed scheme results in improved performance of progrssive transrnission as compared to the conventional rectangular Wavelet tran.fonn coding schemes. The main contribution of this paper is its unique approach which rejects the noisy background rather than considering it for lassy compression as proposed in most of the recent schemes.This rejection of unwanted information results in considerable decrease in bit rate. Another contribution is object based 3-0 coding which is but of scope of baseline JPEG2000.
