"Couple" Image with Different Types of Distortions
|
|
|
|
(a) Original "Couple" image, 512 by 512, 8bits/pixel MSE = 0, Q = 1 |
(b) Impulsive Salt-Pepper Noise MSE = 81, Q = 0.8806 |
|
|
|
|
(c) Additive Gaussian Noise MSE = 81, Q = 0.7039 |
(d) Multiplicative Speckle Noise MSE = 81, Q = 0.7183 |
|
|
|
|
(e) Mean Shift MSE = 81, Q = 0.9947 |
(f) Contrast Stretching MSE = 81, Q = 0.9621 |
|
|
|
|
(g) Blurring MSE = 81, Q = 0.7500 |
(h) JPEG Compression MSE = 82, Q = 0.6761 |
MSE: mean squared error; Q: the proposed universal image quality index
Note: All distorted images have nearly identical MSE, but with different visual quality.
