Imaging by One-Bit Pixels

Before the advent of digital image sensors, photography, for the most part of its history, used film to record light information. In the paper Bits from Photons: Oversampled Image Acquisition Using Binary Poisson Statistics, we study a new digital image sensor that is reminiscent of photographic film. Each pixel in the sensor has a binary response, giving only a one-bit quantized measurement of the local light intensity. We present a theoretical analysis of the performance of the binary sensing scheme, and propose an efficient and optimal algorithm to reconstruct images from the binary sensor measurements.
