"Woman", "Man" and "Barbara" Images with Blurring

(a) Original "Woman" image, 512 by 512, 8bits/pixel

MSE = 0, Q = 1

(b) Blurred "Woman" image

MSE = 200, Q = 0.3483

(c) Original "Man" image, 512 by 512, 8bits/pixel

MSE = 0, Q = 1

(d) Blurred "Man" image

MSE = 200, Q = 0.4123

(e) Original "Barbara" image, 512 by 512, 8bits/pixel

MSE = 0, Q = 1

(f) Blurred "Barbara" image

MSE = 200, Q = 0.6594

MSE: mean squared error; Q: the proposed universal image quality index

Note: All blurred images have almost identical MSE, but with very different visual quality.
