For your videos, Valossa knows if you're happy or sad

Video analytics platform Valossa just launched Val.ai, a platform to help video creators, advertisers and other video boffins figure out what's going on in video. In addition to computer-vision tricks ("Man on a beach", "car interior", "kitten is surprised"), the platform can do sentiment analyses (person is happy / person is sad / person is confused) and even heart rate analysis based on a high-definition video stream alone. "There are many uses for our technology," explains Ville Hulkko, the company's chief commercial officer. Imagine you are looking for a particular piece of footage of a dog and a ball on the beach, for example. If you don't remember when it was taken, you'll spend a long time looking for the correct video clip.
