How to apply nearest neighborhood grouping (NNG) in order to smoothen the spectral response within the pixel’s local neighborhood? In this method a pixel is chosen. Its surrounding eight neighbors are considered for voting. If a class gets four or more votes, then the chosen pixel is assigned to that class. Otherwise the pixel retains its class. How to put this into matlab code?
