        I wish I could help you, but for this I would need a better algorithm. Sorry I don't find a better one.


        hi Martin

        thank you for your quick reply. Don't take me wrong,
        autotrace is a fantastic and powerful software! I am
        actually very happy for being able to extract the central
        lines at all. I truly appreciate your effort for writing and
        sharing it with others!

        Because I did not find detailed descriptions on some
        of the flags, for example, "width-weight-factor", so, I
        am not sure if I used autotrace correctly.

        In your opinion, did I use the proper flags to do
        the tracing for this particular image?

        thanks

        Qianqian

        hi list

        I used autotrace to extract the centerlines from a tubular
        pattern. I found the resulting centerlines often has a
        "seagull-wing" shape at a joint. To illustrate this, here
        is the sample image that I want to trace:

        http://wenq.org/upload/test.png

        the zipped bmp source file is at http://wenq.org/upload/test.bmp.gz

        I used the following command:

        autotrace -centerline -width-weight-factor 0.01 \
        -remove-adjacent-corners -corner-threshold 60 \
        -line-threshold 1.5 -filter-iterations 5 \
        -output-format test.bmp -output-file test.svg

        the output svg looks like this:

        http://wenq.org/upload/test.svg.png

        (the actual svg file is http://wenq.org/upload/test.svg)

        Notice the "wiggly" pattern at the joints.

        My question is: is there an optimized setting in
        autotrace so that I can make these joints more
        straight?

        thanks a lot

        Qianqian
