Figure 3. Comparison of STORM and SCORE at lower SNR where the number of photons per frame from each activated emitter is low and background noise is high.

Figure 3

(a) The dependence of K-L divergence of STORM images on the number of accumulated frames and photons from each activated emitter per frame at high level of background noise (Inline graphic). The values shown are the median of 40 repeats with identical parameters. (b) Same test as (a) on SCORE. (c) A slice of K-L divergence for STORM (red) and SCORE (blue) at 256 photons per frame, indicated as the dashed lines in (a) and (b). (d) Samples of reconstructed images from the two methods at 256 photons per frame and selected numbers of frames.
