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).
