Purdue University Motion Analysis (PUMA) was an early (1991) open-source program.
Puma was the idea of Carol Widule and was brought to life by Krisanne Bothner.

As the field of biomechanics moved away from film to video, propriatary (expensive)
video motion analysis systems were too cost-prohibitive to many. To resolve much of
the expense, Puma was designed to work from COTS components and alleviate the expense
of the overall system. Further, open-source was in its infancy and the idea of
having control over the future development of the software was really intriguing.

After Dr. Bothner graduated, I continued the work, upgrading the Data Translation
hardware from a DT-3152 to a DT3155, implementing newer APIs and making changes to
the flow of the application to support the aquisition of analog frames to digital data.

One Puma was working, meaning each frame of video captured at 30 frames/second was
split into two fields, each field was digitized, captured to disk, displayed on a
monitor and 2-dimensional coordinates of selected points of interest were collected
over the series of fields, the need for kinematic analysis and coordinatation with
kinetic data collected elsewhere was performed. To assist in these data analyses,
I wrote some small C programs to compliment the existing Fortran programs written
by Dr. Widule.
