From a jagged low-res jpeg to a sharper, larger image file, Google researchers have found a way to use machine learning to upscale images to higher resolutions at lightning speed, and it works so fast it could one day be built into your smartphone.
Google is using machine learning to upscale jpeg images much, much faster and often more accurately than current processor-intensive upsampling methods.
Its RAISR program (Rapid and Accurate Image Super Resolution) is still at the experimental stage, but it’s already operating between 10 to 100 times as fast as existing upscaling technology and getting better results in many cases.
The system learns by taking in thousands of pairs of images – one at full resolution, the other downsampled to a jagged, low-res image. It pores over these pairs to work out which filters it can apply to the low-res image’s pixels to get them closest to what’s in the full-res file, taking context into account.
Within about an hour, it’s gone through some 10,000 image pairs and built a pretty decent little knowledge base that it can then apply to any low-res image.
We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @ adafruit.com/blacklivesmatter
