The ultimate purpose of digital image filtering is to support the visual identification of certain features expressed
by characteristic shapes and patterns. Numerous recipes, algorithms and ready made programs exist nowadays
that predominantly have in common that users have to set certain parameters. Particularly if processing is fast
and shows results rather immediately, the choice of parameters may be guided by making the image 'looking
nice'. However, in practical situations most users are not in a mood to 'play around' with a displayed image,
particularly if they are in a stressy situation as it may encountered in security applications. The requirements for
the application of digital image processing under such circumstances will be discussed with an example of automatic
filtering without manual parameter settings that even entails the advantage of delivering unbiased results.
Some of the most perfidious remnants of war are mines threatening not
only combating parties but also innocent civilian lives. Moreover, they make large
areas inaccessible that otherwise could be used economically. This threat exists
even long after cessation of hostile actions. Up to now, the range of tools for humanitarian
demining is confined to mine detection dogs, metal detectors, prodders,
manual excavation tools and mechanical clearance machines (flails and tillers). In
1999, this gave rise for the Board of Directors of the EFNDT to suggest whether
detection methods commonly applied may also be helpful in detecting mines and the
like. It was proposed to transfer existing NDT technology to these areas. As a consequence,
Working Group 5 Antipersonnel Landmine Detection (APLD) was
founded to support this concept. As soon as the group became aware of the fact that
mines were encountered not only in the soil but also elsewhere the name was
changed to Antipersonnel Mine Detection (APMD).
It now is becoming more and more obvious that vicious devises such as mines
and bombs threatening lives everywhere represent an increasing risk to everybody.
In contrast, the particular interest in antipersonnel mine detection is decreasing in
favour of general security and safety. However, all these problems have in common
that such devices need to be detected in time, i.e. before they become effective. This
gives reason to extend the scope of the existing Working Group 5 accordingly. It is
of advantage to exchange existing knowledge and there is a chance to keep the
awareness of the mine problem alive by this way.
