| Abstract: |
If we could tell authentic from counterfeit or adulterated drugs and foods just by looking at them, we could save money and lives every year, especially in the developing world, where the problem is worst. Unfortunately, the technologies that can detect what a sample is made of are expensive, energy-intensive, and largely unavailable in regions where they are needed most. This may change with a simple new technique developed by engineers from the University of California, Riverside that can detect fake drugs from a video taken as the sample undergoes a disturbance. If you’ve ever used online photo tools, you’ve probably seen how these tools use image analysis algorithms to categorize your photos. By distinguishing the different people in your photos, these algorithms make it easy to find all the photos of your daughter or your dad. |
