Abstract:
We present the minimalist camera (mincam), a design framework to capture the scene information with minimal resources and without constructing an image. The basic sensing unit of a mincam is a ‘mixel’ — an optical photo-detector that aggregates light from the entire scene linearly modulated by a static mask. We precompute a set of masks for a configuration of few mixels, such that they retain minimal information relevant to a task. We show how tasks such as tracking moving objects or determining a vehicle’s speed can be accomplished with a handful of mixels as opposed to the more than a million pixels used in traditional photography. Since mincams are passive, compact, low powered and inexpensive, they can potentially find applications in a broad range of scenarios.
