The National Institutes of Health (NIH) is working on a solution to a problem faced by a growing number of Americans as the population ages and relies more on prescription drugs: “What is this pill?” Much in the way a Google image search looks for similar images in Google’s vast caches, the NIH’s National Library of Medicine (NLM) desires a tool to match users’ smart phone photos of mystery pills with hi-res images in the NLM’s existing RxIMAGE database of over 3,000 prescription pills and capsules. If successful, such a tool could not only prevent overdoses, but cut down on waste when unidentified drugs are discarded by those who conclude it’s better to be safe than sorry.
