Opening of an image. The opening is defined as an erosion with the structuring element followed by a dilation with the symetric of the structuring element. Incorrectly, it is often defined as an erosion followed by a dilation, which is only true if the structuring element is symetrical.

Parameters:

iterations - number of iterations to be performed with the structuring element
binary - if true specialized binary operations are used (may be interesting especially in 3D, and/or for a large number of iterations)
