Generate a salt-and-pepper noise distribution.
sp_distribution generates a noise distribution with the values 0 and 255. The parameters PercentSalt and PercentPepper determine the percentage of white and black noise pixels, respectively. The sum of these parameters must be smaller than 100. Usually, the result Distribution is used as input for the operator add_noise_distribution.
|
PercentSalt (input_control) |
number -> real / integer |
| Percentage of salt (white noise pixels). | |
| Default value: 5.0 | |
| Suggested values: 1.0, 2.0, 5.0, 7.0, 10.0, 15.0, 20.0, 30.0 | |
| Typical range of values: 0.0 <= PercentSalt <= 100.0 | |
| Minimum increment: 0.1 | |
|
Recommended increment: 1.0 | |
| Restriction: (0.0 <= PercentSalt) && (PercentSalt <= 100.0) | |
|
PercentPepper (input_control) |
number -> real / integer |
| Percentage of pepper (black noise pixels). | |
| Default value: 5.0 | |
| Suggested values: 1.0, 2.0, 5.0, 7.0, 10.0, 15.0, 20.0, 30.0 | |
| Typical range of values: 0.0 <= PercentPepper <= 100.0 | |
| Minimum increment: 0.1 | |
|
Recommended increment: 1.0 | |
| Restriction: (0.0 <= PercentPepper) && (PercentPepper <= 100.0) | |

sp_distribution is reentrant and processed without parallelization.
