((a)–(d)) The histograms of the SSIM maps. (e) Color map used to show the SSIM maps, where blue color indicates SSIM indexe qual to 1.0 and red color indicates SSIM index lower than 0.95. The MSSIM index achieves value 1.0 if and only if the two images being compared are equal.

(a) DPCM, MSSIM = 0.9852

(b) JPEG-LS Near 2, MSSIM = 0.9705

(c) CCSDS-IDC Int Bpp = 1.0, MSSIM = 0.9854

(d) JPEG-XR “All, QP = 10”, MSSIM = 0.9937
