"Goldhill" Image with Different Types of Distortions
|
|
|
|
(a) Original "Goldhill" image, 512 by 512, 8bits/pixel MSE = 0, Q = 1 |
(b) Impulsive Salt-Pepper Noise MSE = 120, Q = 0.8290 |
|
|
|
|
(c) Additive Gaussian Noise MSE = 121, Q = 0.6151 |
(d) Multiplicative Speckle Noise MSE = 121, Q = 0.6758 |
|
|
|
|
(e) Mean Shift MSE = 121, Q = 0.9928 |
(f) Contrast Stretching MSE = 121, Q = 0.9498 |
|
|
|
|
(g) Blurring MSE = 122, Q = 0.5080 |
(h) JPEG Compression MSE = 117, Q = 0.4963 |
MSE: mean squared error; Q: the proposed
universal image quality indexNote: All distorted images have nearly identical MSE, but with very different visual quality.
