Detecting Heart Disease with Your Phone.

Researchers have developed algorithms that can detect imperceptible changes in facial blood flow from self-shot videos using the front-facing cameras on smartphones, which could be a cheap and effective way of identifying patients who need further investigation for heart disease. Another team of Chinese scientists have developed deep-learning algorithms that can pick up on other signs of heart health from four pictures taken using a smartphone. There are also hopes that smartphones could even provide a cheaper and more portable way of diagnosing harder to spot heart conditions.
