Latest Patents:

Raskar's latest patents showcase his groundbreaking work in two pivotal areas: secure training of multi-party deep neural networks and improved imaging through scattering media.

1. Secure training of multi-party deep neural network:

This patent focuses on preserving data privacy while training deep neural networks involving multiple entities, Alices and Bobs. By employing a "split" neural network, the approach ensures that Bob, the outside computing entity, can assist in computations without accessing Alices' data directly. The network consists of an Alice part, comprising at least three neural layers, and a Bob part, comprising at least two neural layers. This novel architecture allows efficient collaboration while safeguarding data privacy.

2. Methods and apparatus for improved imaging through scattering media:

Raskar's second patent addresses the challenge of imaging scenes obscured by fog or scattering media. The patent proposes using a time-resolved light sensor, such as avalanche photodiodes, to collect reflected light. By leveraging a probabilistic algorithm that accounts for the different distribution of photon arrival times between the fog and the target, the imaging system obtains both reflectance and depth information of the obscured scene. Additionally, the system employs techniques like spatial and temporal regularization, as well as deblurring, to enhance the quality of the captured images.

Career Highlights:

Throughout his illustrious career, Raskar has held key positions at renowned institutions and companies. Notable highlights include his work as an Associate Professor at MIT and a research scientist at Mitsubishi Electric Research Laboratories, Inc.
