WebMorphological reconstruction by dilation is similar to basic morphological: dilation: high-intensity values will replace nearby low-intensity values. The basic dilation operator, however, uses a footprint to: determine how far a value in the input image can spread. In contrast, reconstruction uses two images: a "seed" image, which specifies the ...
In morphological opening , the erosion operation removes objects that are smaller than structuring element B and the dilation operation (approximately) restores the size and shape of the remaining objects. However, restoration accuracy in the dilation operation depends highly on the type of structuring element and the shape of the restoring objects.
