How Google Cracked House Number Identification in Street View

Using a neural network, Google can identify street numbers on houses in France.  Fascinating article in MIT Technology Review this year about how their engineers did it.

“Google Street View has become an essential part of the online mapping experience. It allows users to drop down to street level to see the local area in photographic detail.But it’s also a useful resource for Google as well. The company uses the images to read house numbers and match them to their geolocation. This physically locates the position of each building in its database.That’s particularly useful in places where street numbers are otherwise unavailable or places such as Japan and South Korea where streets are rarely numbered in chronological order but in other ways such as the order in which they were constructed, a system that makes many buildings impossibly hard to find, even for locals.
