Automatic Image Retouching on Your Phone
A new system that can automatically retouch images in the style of a professional photographer can run on a cellphone and display retouched images in real time.

Researchers at the Massachusetts Institute of Technology (MIT) and Google have developed a cellphone-based system that can automatically retouch images.
The researchers say the energy-efficient, machine-learning system can display the retouched pictures in real time and accelerate existing image-processing algorithms.
For every new task the system learned, it was trained on thousands of pairs of images, both raw and retouched.
The research builds on an earlier MIT project in which a cellphone would transmit a low-resolution version of an image to a Web server, which would return a "transform recipe" that could be used to retouch the high-resolution version of the image on the phone, lowering bandwidth consumption.
Most of the image processing is handled on a low-resolution image to further boost efficiency.
"This technology has the potential to be very useful for real-time image enhancement on mobile platforms," says Google's Jon Barron.
The research will be presented this week at the ACM SIGGRAPH conference in Los Angeles.
