For Max, you can use findpeaks() function. And for Min, it's the same function but with negative data (i.e. -x).

findpeaks() works only with vectors (see the help), not with 2-D arrays.

You can use the functions imregionalmax() and imregionalmin() in the Image Processing Toolbox.

Input is the name of a built-in function so don't use that for your variable name. Try this:
localMaxImage = imregionalmax(grayImage);
localMinImage = imregionalmin(grayImage);
