"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 index
Note: All compressed images have similar MSE, but with very different
visual quality.
