Figure 4: Images with different SNRs.
From: Single-pixel imaging by means of Fourier spectrum acquisition
The images are reconstructed from (a) detector 2 with environmental illumination of fluorescent lamps, (b) detector 1 with environmental illumination of fluorescent lamps and (c) detector 1 without any environmental illumination, respectively. The SNRs are computed according to the equation (S9). Periodic noise reduction has been applied. Scale bar, 2 cm.
