Hospital-acquired infections are a pesky problem and around one in 25 hospital patients have at least one healthcare-associated illness at any given time. To combat this issue, a research team based at Stanford University turned to depth cameras and computer vision to observe activity on hospital wards -- a system that could be used to track hygienic practices of hospital staff and visitors in order to spot behaviors that might contribute to the spread of infection. The work is being presented at the Machine Learning in Healthcare Conference later this week. The researchers placed depth cameras in various places -- in hallways, patient rooms and around hand sanitizing dispensers -- across two different hospital wards. Video was collected over the course of one very busy hour in the hospital and 80 percent of the video was used to train tracking algorithms while the other 20 percent was used to test the algorithms post-training. During that hour, 170 people entered patient...
