Comparative Study on MATLAB based Joint Photographic Experts Group Image Size Reduction Using Shearlet and Wavelet Transform for X-Ray Images with Potential Hospital Data Storage Application
Abstract
Aim: The aim of this paper is to compress the x-ray images using wavelet and shearlet transform
and compare the compression ratios to find a better transform. Materials and Methods: 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. Results: Wavelet based CR
was seen to be higher mean (6.61) when compared to shearlet (4.025). Hence wavelet transform
seems better transform for compressing X-Ray images. Conclusion: We observed that wavelet
transform seems to have a better compression ratio compared to shearlet transform (P=0.28,
P<0.05, independent sample t-test).
