I have a binary array that has thousands of irregularly shaped objects in it. Occasionally, the corners of two objects touch. How can remove that pixel so that this one object becomes 2 objects? I know i can erode all objects but that affects the area of the objects, which is important to me.

If you use four connected processing, it won't be touching. Look for that in the input. Most of the functions (e.g. bwlabel) assume 8-connected but will let you specify.
