Ciao,

I want to extract the contour of lungs in CT-images. Therefore I created
an black/white image, where the threshold can be selcted by the user. I
want to overlay the resulting contour of black/white image with the
original image. Unfortunatly the returned contour is tiny and is not
congruent with the original. How can I magnify the contour and fit it in
the given frame?
So far my code is looking like that:

contour, contrast,path_xy=x,y,Path_info=pafo

FOR I=0,(n_Elements(pafo)-1) DO BEGIN
s=[ indgen(pafo(I).N),0]
Ploats,xy(*,pafo(I).Offset + s),/Norm
ENDFOR

Regards, Ruth
