  • Re: State of the Art in Markerless Motion Tracking

    The website for Organic Motion is very impressive, but as far as I can
    tell, they don't offer any sort of validation studies for the accuracy
    and precision of their 3D motion data. You can download motion data
    files (I have not looked at them yet) from their site, but it does not
    appear that there are any traditional marker-based data sets to which
    one could compare the data from their marker-less capture.

    I also am interested to hear from anyone who's used the system, or
    better yet, has done a validation study. My initial impression is
    that the system may be better suited for the entertainment industry
    than it is for the biomedical/life-sciences industry, when compared to
    traditional (albeit still flawed) marker-based motion capture
