"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 index
Note: All distorted images have nearly identical MSE, but with
very different visual quality.
