Goggles attempts this feat by analyzing images using various mathematical algorithms. Then it compares extracted information (called features) with its expansive image database to find any possible matches. Items with a lot of texture and recognizable feature points are recognized almost immediately. Capture an image of a Coke can or the Golden Gate Bridge, and you'll likely see an accurate description in your search results. Bright, colorful product packaging, for instance, is pretty simple to recognize. Less commonly known places. Things aren't as easy for Google to discern. Because Goggles relies on your smartphone's camera, object and text identification is sometimes harder than it should be. You can give Goggles a big assist by taking your pictures in good light, holding the camera steady and using a decent resolution setting. Grainy or blurry photos are a recipe for Goggles failure. To further improve results, Goggles has a feature that helps you crop the image, leaving the most pertinent (and recognizable) elements for analysis.|Virtual reality (VR) headsets have been around since the 1960s, and as you would expect, they have evolved and gotten better over the years. But they really haven't caught on as viable consumer products. You may have seen the occasional VR headset in an arcade, and home models have popped up now and again to be snatched up by enthusiasts and then fizzle out, but at the moment, they're more at home in research labs or military training facilities. Despite their continued existence and the obvious cool factor, they haven't become as common as our speculative fiction led us to believe they would have been by now. There are lots of possible reasons, including their low resolution, tendency to cause simulation sickness and the prohibitive cost of the better models. But conditions have changed. Graphics processing, motion tracking and display technologies, among other things, have all improved vastly since the inception of VR, and everything has gotten smaller and cheaper. We now have far more powerful processors, a myriad of sensors and small high-resolution displays that are bringing consumer VR into the realm of possibility. The short answer can be chalked up to the measures taken to stop the spread of COVID-19 - social distancing, handwashing, mask wearing, wiping down surfaces and following "safe at home" orders, says Dr. Ellen Eaton, an assistant professor of medicine in the University of Alabama at Birmingham (UAB)'s Division of Infectious Diseases, and author of the Facebook page Dr. Ellen Eaton Coronavirus Updates. Those efforts worked because there are some commonalities between the seasonal flu and COVID-19. Both are contagious respiratory viruses, meaning they affect the lungs and breathing. They also most often spread from person-to-person, such as when someone inhales or swallows droplets that fly into the air when an infected person coughs, sneezes or talks. With both viruses, infected individuals can spread the virus before symptoms present. But why did those efforts have more of an impact on the number of flu cases compared to COVID-19 cases? explosion en hidalgo hoy
