    • ST1791: Single Pixel Imaging

      The Computational Sensing team at MERL is seeking motivated and qualified individuals to design sensing mechanisms and develop algorithms that perform high quality image and video reconstruction from a single pixel detector. The project goal is to improve the performance and develop robust methods that can reduce the number of snapshots required for image formation. Ideal candidates should be Ph.D. students and have solid background and publication record in any of the following, or related areas: compressed sensing, imaging inverse problems, large-scale optimization, plug-and-play priors, learning-based modeling for imaging, learning theory for computational imaging. Publication of the results produced during our internships is expected. The duration of the internships is anticipated to be 3-6 months. Start date is flexible.
