Perform the morphological closing operation on a binary image in respect with a defined neighborhood size.
[C] = NL_V_ClosingW(I,W)
Binary matrix.
Window size.
Closing matrix.
NL_V_ClosingW performs the morphological closing operation on the binary image I. The output matrix is stored in C. The closing operation consists of Erosion(Dilation(I)) (WIKIPEDIA).
