ImageDev

RandomImage3d

Creates a new three-dimensional image with random values having an equidistribution.

Access to parameter description

RandomImage3d creates an image with random values that follow a uniform distribution.
The output image intensity values are included in the range $\left[Mean-\frac{Range}{2}~..~Mean+\frac{Range}{2}\right]$.
Where $Mean$ and $Range$ are input parameters of the algorithm.
The image histogram is flat, which means that each intensity has an equiprobability to occur.

The type of the output image is set by an enumerate as detailed in the Data Type Management section.
