Hi Chris! Nice guess :) You believed correct regarding the shape, so calculating it this way will be my "control".
Now, my next question: Can PDL be used as an image analyzing tool to identify A_s (number of pixels within the boundary) if A_s is white and the surrounding is black?

If that is the case then the volume is the >sum of the volumes of the middle (M), the curved sides (S), and the corners >(C). The volume of the middle would be L*L*h where h is the height from the image. The volume of the sides would be L*A_s where A_s is the area of the end of your image where the corners start. If you relocate the corners, they form a solid of revolution. You can calculate that from the height of the profile in the image h(r) and integration. --Chris On Wed, Jan 30, 2013 at 8:16 AM, Edvardsen Kåre <[email protected]> wrote: > Before spending effort unnecessary, I wonder if there is any simple > way to calculate the volume of an object by analyzing a picture of it? > > > > Attached pdf show the shape. > > > > Cheers, > > Kåre > > > > Dr. Kåre Edvardsen > > Associate Professor > > Dep. of Scientific Engineering and Safety > > University of Tromsø > > [email protected] > > +47 77 66 02 69 > > +47 90 74 60 69 > > > > > _______________________________________________ > Perldl mailing list > [email protected] > http://mailman.jach.hawaii.edu/mailman/listinfo/perldl > _______________________________________________ Perldl mailing list [email protected] http://mailman.jach.hawaii.edu/mailman/listinfo/perldl
