Performance Evaluation of Noise Reduction Filters for Color Images through Normalized Color Difference (NCD) Decomposition

Table 2

Advantages of our method over the classical MSE and MAE evaluations (“Parrots” image corrupted by fixed-value impulse noise and filtered by 5-point and 5×5 vector median operators).

Image	MSE	MAE	NCDimp (×10^2)	NCDdis (×10^2)

Figure 6(c)	77	3.6	1.58	2.08
