Facebook introduced machine learning technology to recognize objects in pictures, then describe photos aloud which will help blind community to visualize it.

People who are visually impaired or blind can see photos uploaded on Facebook by scanning scenes with smartphone cameras or specially equipped eyewear.
The feature was being tested on mobile devices powered by Apple iOS software and which have screen readers set to English.
Facebook planned to expand the capability to devices with other kinds of operating systems and add more languages, according to King, who lost his vision as a US college student studying electrical engineering.
The technology works across Facebook’s family of applications and is based on a "neural network" taught to recognize things in pictures using millions of examples.
More than two billion pictures are shared daily across Facebook, Instagram, Messenger and WhatsApp, King said.
The Silicon Valley-based social network said that it was moving slowly with the feature to avoid potentially offensive or embarrassing gaffes when it comes to automatically describing what is in pictures.
The Facebook technology made its debut less than a week after Microsoft enticed software developers with a suite of offerings that let them tap into the power of cloud computing, big data, and machine learning.
The Cortana Intelligence Suite boasted the ability to let applications see, hear, speak, understand and interpret people’s needs.
Microsoft said that a "Seeing AI" research project was underway to show how those capabilities could be woven into applications to help people who are visually impaired or blind better learn what is around them, say by scanning scenes with smartphone cameras or specially equipped eyewear.
