I would be interested in seeing this article (and morphological image processing) fleshed out a little. I have studied morphological image processing as applied to binary images, and the extension to greyscale and in particular how it relates to lattice theory is far from obvious.

I have just made a modification to this article; and intent it to be a first of a number of modifications. I have extensive experience on this field, and find the page to be kind of poor at this point, so I intend to add material substantially over time. Renatokeshet ( talk) 06:47, 16 May 2008 (UTC)
The figure that illustrates erosion is not correct: the center of the eroding disk should walk on the boundary of the outer rectangle. Sprocedato ( talk) 14:11, 13 August 2009 (UTC)
The section although correct is hard to understand. I found the following link to be very useful in describing the concept. It seems it is written as a refresher for the academic.

I'm planning to do a new overhaul to this article. It will take a couple of months, but here is the plan:
Even after the overhaul, there will be still a lot of work in illustrating and expanding the examples. But then the article will be somewhat more directed to the general audience, rather to experts in image processing. Comments/remarks/ideas/objections? Renato ( talk) 16:15, 8 August 2010 (UTC)
I have a trouble with the equations of the dilation in grayscale morphology: isn't it rather than ? It does not seem to be coherent with the first grayscale equation of the dilation (if we set z = x - y). Plus is coherent with the chap2 of the slides of Jean Serra (p.19). Same for the erosion. What do you think ? RaffiEnficiaud ( talk) 23:43, 26 August 2010 (UTC)
Do you think the sentence "Dilation is the opposite of the erosion" is accurate ? One may think about a reversible process, which the pair ero/dil does not meet (both transforms loose some information either on the foreground or the background)

I think there should be some numeric examples, particularly of grayscale morphology. The notation isn't particularly clear- consider dilation for example. f(x) is defined as an image, but in the equation, f(y) is used, followed by f(x-z). y is defined as an element of E, which is further defined as any real in a Euclidean space. So, to me the implication is to take some function f, apply it to every real that is a member of a Euclidean space, and then take the same function and apply it to x-z. Do that for all y, and take the highest sum, and do what with it? I think a rudimentary example with a small structuring element and numeric image would help clarify.
