Function File: imopen (img, SE)

Perform morphological opening.

The matrix img must be numeric while SE can be a:

• strel object;
• array of strel objects as returned by ‘@strel/getsequence’;
• matrix of 0’s and 1’s.

The opening corresponds to an erosion followed by a dilation of img, using the same SE, i.e., it is equivalent to:

imdilate (imerode (img, se), se);
