Title:
- Coded Lens: Using Coded Aperture for Low-cost and Versatile Imaging

Abstract:
We propose Coded Lens, a novel system for lensless photography. The system does not require highly calibrated optics, but instead, utilizes a coded aperture for guiding lights. Compressed sensing (CS) is used to reconstruct scene from the raw image obtained through the coded aperture. Experimenting with synthetic and real scenes, we show the applicability of the technique and also demonstrate additional functionality such as changing focus programmatically. We believe this will lead to a more compact, cheaper and even versatile imaging systems.
