1 FIELD_FIND
        FIELD_FIND

    Makes the field labelling of   an   image,   i.e.    identifies   connex
    areas with image values higher than a given threshold and attribute them
    a number.  The result is an image (of same size as the  input  one),  in
    which  the  value  of  a  pixel  is  the number of the field to which it
    belongs.  A zero value is attributed to pixels under the threshold.

    Note  that  blanked  pixels   may    adversely    affect    the    field
    labelling...
