Abstract
- The aim of this paper is to compress the computed tomography (CT) scan images using wavelet and shearlet transform and compare the compression ratios to find a better transform among them for the target application. The sample size of each group was 30 and the total sample size was 60. Compression ratios (CR) were generated for images based on the transform used for size reduction. Wavelet based CR appeared to be of higher mean (6.6146) when compared to shearlet (4.02). Hence wavelet transform seems to be a better transform for compressing CT scan images. We observed that wavelet transform seems to have a better compression ratio compared to shearlet transform (P<0.001, independent sample t-test). [ABSTRACT FROM AUTHOR]
