One thing to remember is, probably all the track images posted here on Bushcraft uk were found over a considerable period of time, on good ground under favourable light conditions and nearly always showing a complete track, Complete tracks are relatively easy to ID, so to be of any practical benefit "at least to the experienced tracker" it would have to reconstruct and ID incomplete or partial tracks, and run as an apps on something like a digital camera or mobile phone.
As to the benefits it could be helpful for new or young trackers, gamekeepers,wildlife survey teams,any of the usual outdoor type,either ID it on the spot or take an image and ID it later and it home.
You may find this book a good starting point. It has a short section on cyber-tracker software,which may be of some interest.

Overlapping the traditional and fundamental tracking skills of observation and interpretation,and crossing over to Holistic tracking, tuning into the natural world with basic exercises designed to develop Increasing and refine sensory awareness and intuition. With chapters covering journaling, ecology mapping, animal runs, trailing, aging tracks and sign, birdsong and storytelling and finally a chapter on modern tracking tools cyber-tracker software, camera traps, digital photography and video recording, soot trays and trapping..........
Gait pattern recognition may possibly be your easiest route to follow initially for the development of computer software and algorithm programs however. Sorry but just in case you are new to tracking,or unfamiliar with the terminology, “Gait or gait patterns” are the consistently regular and predictable footfall placements at a set speed in the locomotion all quadruped animals,"walk, trot, run, canter, gallop etc.
If it’s small, lightweight, waterproof and works you could be on a winner.
Good luck.
