Abstract

We demonstrate a computational image reconstruction using only a bare CMOS sensor and accidental imperfections. Once sensor is calibrated using LED array, complex objects displayed not only on LED array but also on LCD display could be reconstructed. We are now pursuing the direct use of raw sensor images in machine learning without reconstruction.
