On the left is an example of the simulated mask used in this paper, the same random pattern is replicated to fill the image. On the right, for comparison, is a random mask. Black mask pixels would block the signal from the sensor, while white mask pixels allow the electrons to pass normally. Using a replicated mask is equivalent to a fully random mask in this CS framework, since each patch is inverted individually. For simulations, a replicated mask reduces computation since only a few matrix inverses must be computed (one for each shift of the mask) and then applied to all of the patches
