SelectiveOpening2d
Opens objects of a two-dimensional binary image conditionally to a local constraint.
Access to parameter description
For an introduction:
It can be applied only on binary images. Using a threshold of 1 amounts to applying a standard morphological opening.
This operator is smoother than the classic opening, and softens the appearance of the structuring element in the filtered image.
