MEDICAL IMAGE COMPRESSION USING VIEW COMPENSATED WAVELET TRANSFORM

N. Sathiyanathan

Abstract


Volumetric images have great impact over the past few years in medical and industrial application. This paper presents a new architecture for compression and decompression. 2-D computer tomography has been used as an input. In order to obtain high quality image, Lifting based View Compensated Wavelet Transform (VCWT) technique has been proposed. The main contribution of this paper is the development of a “view compensation” scheme that gives excellent compression performance and reduces the complexity by using JPEG 2000. The quality of reconstructed images is measured with PSNR value.
