File Information

This is an implementation of a traditional Niblack local image thresholding with an integral image method, which guarantees constant computation time regardless of the neighborhood size.

The method can be described like:
  if pixel > (mean + k * standard_deviation)
     pixel = object;
     pixel = background;

MATLAB release MATLAB 6.5 (R13)
