Table 1 shows image quality values for the original, 50-frame averaged, CDWT, and DD-CDWT wavelet denoised images. The values of CNR, ENL, SNR, , and SSIM for seven sample images show significant improvement. A paired -test was performed for comparison of CDWT and DD-CDWT wavelet denoising algorithms with statistical significance given by values of . Comparison of CNR, ENL, SNR, , and SSIM results in values of 0.0083, 0.1633, 0.3788, 0.0001, and 0.0001, respectively. The values for ENL and SNR are considered not to be statistically significant. However, the values for CNR, , and SSIM are considered to be statistically significant.
