WebIn other words, closing (opening) of a binary image can be performed by taking the complement of that image, opening (closing) with the structuring element, and taking the complement of the result. The hit and miss transform (see also HIPS2 web page) allows to derive information on how objects in a binary image are related to their surroundings. WebIn this way we implement an open-close filter. In this case, the structuring element must be not only large enough to eliminate the noise granules but also small enough to fit between salt holes. If the structuring element does not fit between two salt holes, during opening the erosion by B will create larger holes, thus degrading the image foreground.

The basic morphological operators are erosion, dilation, openingand closing. MM was originally developed for binary images, and was later extended to grayscalefunctionsand images. The subsequent generalization to complete latticesis widely accepted today as MM's theoretical foundation.
