Dear all,
my goal would be to apply some function on a local environment of size K x K x K where K is bigger than 1 and odd. For example, if K = 3, it would be nice to apply some function "func" on such an environment around each n-dimensional position within the n-dimensional array. So, for K = 3 and the position (1,1,1) if a 3D array, one would collect the array values at the positions X = [(0,0,0),(0,0,1),(0,0,2),(0,1,0),...(2,2,2)] (K**3 = 27 in total in this example) and yield those values to "func". The result value at position (1,1,1) in the output array would be y = func(X). The same would apply for all entries excluding the padding area (or according to some padding policy).
