Performs full blind estimation algorithm published by Villarrubia. This
function converts all fields into form requested by "morph_lib.c" library,
that is almost identical with original Villarubia's library. Note that the
threshold value must be chosen sufficently high value to supress small
fluctulations due to noise (that would lead to very sharp tip) but
sufficiently low value to put algorithm at work. A value similar to 1/10000
of surface range can be good. Otherwise we recommend to start with zero
threshold and increase it slowly to observe changes and choose right value.
