If method_index is 3, the intensities of the four closest pixels in spectral direction are considered and
their mean intensity is computed for each bad pixel as:

If method_index is 4, the local clean (low_rejection, high_rejection) standard deviation
)
_
in a box (llx, lly, urx, ury) is computed. Then the difference of the pixel and the median of the nearest
neighbours is computed by using the eight closest pixels of every pixel.

The previous operations are repeated for (iterations) times to be able to consider small clusters of bad
pixels.
