"Tiffany", "Lake" and "Mandrill" Images with JPEG Compression
|
|
|
|
(a) Original "Tiffany" image, 512 by 512, 8bits/pixel, MSE = 0, Q = 1 |
(b) JPEG compressed "Tiffany" image MSE = 165, Q = 0.3709 |
|
|
|
|
(c) Original "Lake" image, 512 by 512, 8bits/pixel MSE = 0, Q = 1 |
(d) JPEG compressed "Lake" image MSE = 167, Q = 0.4606 |
|
|
|
|
(e) Original "Mandrill" image, 512 by 512, 8bits/pixel MSE = 0, Q = 1 |
(f) JPEG compressed "Mandrill" image MSE = 163, Q = 0.7959 |
MSE: mean squared error; Q: the proposed
universal image quality indexNote: All compressed images have similar MSE, but with very different visual quality.
