It'due south no cloak-and-dagger that smartphone SoCs don't scale as well equally they once did, and the overall charge per unit of performance comeback in phones and tablets has slowed dramatically. One area where companies are still delivering significant improvements, even so, is cameras. While this apparently varies depending on your manufacturer, companies like Samsung, LG, and Apple keep to deliver year-on-twelvemonth improvements, including higher MP ratings, multiple cameras, improved sensors, and features similar optical image stabilization. There'south still a gap between DSLR and telephone cameras, but it's been narrowing for years. And if recent work from Intel and the University of Illinois Urbana-Champaign is any proof, machine-learning tin solve a problem that bedevils phone cameras to this twenty-four hour period: low-low-cal shots.

Don't get me incorrect, the depression-low-cal capabilities of modern smartphones are excellent compared with where we were just a few short years ago. But this is the sort of area where the difference between phones and a DSLR becomes apparent. The gap between the two types of devices when shooting static shots outside is much smaller than the divergence you'll meet when shooting in low low-cal. The team built a machine learning engine by creating a data set of short exposure and long exposure depression-light images (these were used for reference). The study states:

Using the presented dataset, nosotros develop a pipeline for processing low-light images, based on stop-to-cease training of a fully-convolutional network. The network operates directly on raw sensor data and replaces much of the traditional image processing pipeline, which tends to perform poorly on such data.

The team has put a video together to explain and demonstrate how their technique works, as shown beneath:

We'd recommend visiting the site if y'all want to see high-resolution images of the before and later, merely the base images being worked with aren't only "low light" — the original shots are, in some cases, almost entirely black to the naked center. Existing image software struggles to make much out of these kind of results, fifty-fifty when professional processing is used.

While there's notwithstanding some inevitable mistiness, if you click through and look at either the newspaper or the high-resolution default shots, the results from Intel and Champagne-Urbana are an guild of magnitude better than annihilation we've seen earlier. And with smartphone vendors jockeying to build auto intelligence capabilities into more devices, information technology's entirely possible that nosotros'll encounter more than and more products bringing these kinds of capabilities to marketplace in phones and making them bachelor to ordinary customers. I, for one, welcome the idea of a smarter photographic camera — preferably one able to correct for my laughably terrible photography skills.
