iclose

closing

out = iclose(im, se, options) is the image im after morphological closing with the structuring element se. This is a morphological dilation followed by an erosion.

out = iclose(im, se, n, options) as above but the structuring element se is applied n times, that is n erosions followed by n dilations.

Notes

• For binary image a closing operation can be used to eliminate small black holes in white regions.
• Cheaper to apply a smaller structuring element multiple times than one large one, the effective structuring element is the Minkowski sum of the structuring element with itself N times.
• Windowing options of IMORPH can be passed. By default output image is same size as input image.
