Shape Adaptive Integer Wavelet Transform based coding scheme for 2-D/3-D MR Images

摘要

Data compression is useful in reducing the storage and/or transmission bandwidth equirements of medical images. In the medical image scenario, lossy compression chemes are not generally used. This is due to a possible loss of useful clinical information which may influence diagnosis. Hence there is a need for efficient lossless compression schemes for medical data. We propose a new Shape Adaptive Integer Wavelet Transform (SAIWT) based progressive transmission coding scheme for 2-D and 3-D brain MRI.
