Description
TExpander implements a neighborhood operation similar to morphological dilation. However, unlike ordinary dilation, where the structuring element is added to the color samples, the expand operation will multiply the weights. We define this operator as
where f is a sampler and b is a structuring element. The structuring element is defined by the Kernel property of the class. See topic about Sampling and Rasterization for more info.
