Estimating Color and Texture Parameters for Vector Graphics
Diffusion curves are a powerful vector graphic representation that stores an image as a set of 2D Bezier curves with colors defined on either side. These colors are diffused over...

Indoor localization without infrastructure using the acoustic background spectrum
We introduce a new technique for determining a mobile phone’s indoor location even when Wi-Fi infrastructure is unavailable or sparse. Our technique is based on a new ambient so...
