and can connect closely placed regions.

You can create the opening filter by adding erosion filter followed by dilation filter using
the same structuring element for both operations.
Open eliminates foreground features smaller than the structuring element,
smoothed contours, suppresses small features in the image, and removes
sharp protrusions of shapes.
You can create the closing filter by adding dilation filter followed by erosion filter using the
same structuring element for both operations.
Close eliminates background features smaller than the structuring element,
and blocks up narrow
channels in shapes.
