Add module: Morphological reconstruction

[tischi]

Morphological reconstruction is super powerful, e.g., can be used for local maxima detection: https://github.com/ijpb/MorphoLibJ/issues/47

• start from function f (-> the dark curve)
• consider function f-h, where h is the contrast or dynamic (-> the dashed curve)
• perform morphological reconstruction by dilation of (f-h) under f (-> the blue region)
• compute the regional maxima of the reconstruction (-> the dark blocks)

But also for local background subtraction....

Don't get it. You first perform a morphological operation and then maxima detection?

We should discuss about this. I am not sure if I understand everything but could one not disentangle the terms?

I understand morphological reconstruction applied on a binary image as CCA with seeds. This has quite nice properties as you can remove objects touching borders or fill hole. For instance you perform morphological reconstruction with seeds = border or a morphological reconstruction on the inverse.

Attribute filtering is a morphological reconstruction with on top of it some selection criteria.
