    Gigapixel Computational Imaging

We are building a new breed of cameras with increased functionality and performance that will transform the way cameras are built in coming decades, from low-end consumer imagers to high-end scientific instruments. Our research is in the emerging field of computational photography, which combines expertise in optics, image processing, computer vision, and computer graphics. We design, model and build systems that combine sensors, displays, and novel optical elements. The Computational Photography Lab is led by Prof. Oliver Cossairt, Assistant Professor in the Department of Electrical Engineering and Computer Science at Northwestern University.

We are currently hiring postdocs with expertise in computational imaging, image processing, optics, and computer vision. Please send inquiries to ollie(Replace this parenthesis with the @ sign)eecs.northwestern.edu.
