I have a problem using tesseract with german fraktur.

firstly the text to be ocr'd is real printed text of about 1930.
the printing is a little dirty i.e. there are little points and strokes 
between 
the letters.
though these are far smaller than the other letters, they are interpreted 
as 
normal letters.

Is there a possibility to give parameters to tesseract that it 
. either should neglect letters which do not fit the majority of the other 
  letters, 
. or it should only use letters in a given range of size
. or to firstly make the boxes, 
  then correct the boxes, by hand or program,
  finally translate using the corrected boxes

a solution with a dictionary is not possible, because the text consists of 
only 
names of persons and locations.

Another thing i wonder is:
when i ocr an image from .tiff to .txt
and makebox of the same image
some (few) letters are different recognized!

thanks for help in advance
