  • tpsDIg - free software to manually digitize markers from AVI andMOV video

    I would like to recommend a free software package for
    manually digitizing photogrammetric markers from AVI and
    MOV video files. The program tpsDig, developed by
    Professor F. James Rohlf at SUNY Stony Brook, has been an
    excellent resource for many years for the geometric
    morphometrics community to digitize landmarks from images
    of anatomical structures. Geometric morphometrics is the
    mathematical study of anatomical shape to help describe
    physical differences related to ontogenetic, phylogenetic
    and pathological variations.

    Professor Rohlf has recently updated tpsDig to allow input
    from sequences of images within AVI and MOV multimedia
    files. The program allows the user to open AVI or MOV
    files, manually index through the images, manually digitize
    any number of markers per frame and save the X,Y marker
    locations into an ASCII text file. The only restriction is
    that the multimedia input window must completely show the
    current frame to allow it to be completely captured to the
    digitizing window. Hence, using a larger monitor is
    recommended but not essential. (I use it on my old 486
    laptop with 640x480 resolution and 256 colors.) The
    program can also be used to manually digitize landmarks
    from individual images or a sequence of images in BMP, GIF,
    JPG, PCX, PNG and TIF formats. The program has been
    tested under Win95 and Win98.

    This program can be extremely useful for simple clinical
    gait analysis or pilot studies when used in conjunction
    with new digital cameras capable of saving AVI and MOV
    videos. It can also be used by students in biomechanics
    classes to digitize human movement from lab videos, from
    sports studies or from scientific databases such as CGA
    (Clinical Gait Analysis by Dr. Chris Kirtley at

    To obtain a copy of tpsDig, visit Professor Rohlf's
    morphometrics webpage at

    Then select links for "Software" then "Support routines"
    then "tpsDIG32" to download a self-extracting executable
    file. The executable can install the program in any folder
    of your choice.

    While you are visiting the morphometrics webpage, I
    recommend browsing the site to learn a little more about
    geometric morphometrics, particularly those of you who are
    interested in geometric modeling of anatomy, and 3D
    statistics of anatomical landmarks such as ligament
    attachments and muscle origins/insertions. Additionally,
    you might investigate the MORPHMET listserver, similar to
    our BIOMCH-L discussion forum.

    I strongly recommend this free software and wish to thank
    Professor Rohlf for his continued support of morphometrics
    and now biomechanics.
