RandomJ: Binomial

General Description

This plugin enables you to contaminate images with random numbers generated using a binomial random variable.

Description of Dialog Components

Trials and Probability. The parameters of the probability mass function of the binomial random variable:

Binomial PMF

with "n" being the number of trials and "p" the probability of success per trial. The former must be a non-negative integer and latter a real number in [0,1].

Insertion. The random numbers can be inserted into the image either additively or multiplicatively.

Implementation Details

The generator is based on the algorithm given by Press et al. [1] and uses the Uniform plugin as a source of uniform random numbers. Since the uniform number generator is initialized with a seed derived from the system's current time in milliseconds, the sequence of random numbers will be different for each application of this plugin.
