“Tor operates under the assumption that there’s not a global adversary that’s paying attention to every single link in the world,” Nickolai Zeldovich says. “Maybe these days this is not as good of an assumption.”

By combining the information from the Kinect depth frame in (a) with polarized photographs, MIT researchers reconstructed the 3-D surface shown in (c). Polarization cues can allow coarse depth sensors like Kinect to achieve laser scan quality (b).

Making 3-D imaging 1,000 times better

Algorithms exploiting light’s polarization boost resolution of commercial depth sensors 1,000-fold.

MIT researchers have developed a new biomedical imaging system that harnesses an off-the-shelf depth sensor such as Microsoft’s Kinect. The coloration of these images depicts the phase information contained in six of the 50 light frequencies the system analyzes.

Biomedical imaging at one-thousandth the cost

Mathematical modeling enables $100 depth sensor to approximate the measurements of a $100,000 piece of lab equipment.

MIT researchers have shown that some phone apps engage in “covert communication.” “There might be a very good reason for this covert communication. We are not trying to say that it has to be eliminated. We’re just saying the user needs to be informed,” says Julia Rubin, a postdoc in MIT’s Computer Science and Artificial Intelligence Laboratory.

What are your apps hiding?

Half of the communication connections established by the top 500 Android apps have no effect on user experience.

An example of the Non-Local Variations algorithm that automatically detects and visualizes small deformations between repeating structures in a single image. On the left is the original image. In the right image, the variability in the shape of the corn’s kernels is reduced, and the misalignment of rows is corrected.

Amplifying — or removing — visual variation

Algorithms could offer new tools for graphics software or reveal structural defects.
