RadialFunctionImage2d

Creates a new two-dimensional image by a circular projection of an array of values.

Access to parameter description

This algorithm creates a circular construction of an image from a single array. The resulting image is a radial projection of the input array from the center: I(i,j)=Array(dist((ic,jc),(i,j))) Where (ic,jc) represents the image center and dist is the pointwise distance in pixels.
The output image is necessarily square with a side given as an input parameter.

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