Figure 5
The PSNR and RE results with wavelet, Contourlet, and joint transform for various values of approximate parameter . (a) PSNR of follow-up experiment for various values of . (b) RE of follow-up experiment for various values of . (c) PSNR of T2-FLAIR experiment for various values of . (d) RE of T2-FLAIR experiment for various values of . It can be seen that exhibits reliable results for all cases.
