Figure 3.

Evaluation of EIR with plots of PSNR (a) and SSIM (b). The blue solid circles are the values of evaluation metrics for raw images observed with different imaging rates (exposure times). The orange solid circles are the values of the evaluation metrics for images denoised with N2N with ensemble. The criteria $\mathrm{PSNR}=30$ dB and $\mathrm{SSIM}=0.8$ are plotted as the red dashed lines. The star markers in (a) and (b) correspond the evaluation metrics at 12.5 images/min including Fig. 2c. (c) The ${\mathrm{EIR}}_{\mathrm{PSNR}}$ and ${\mathrm{EIR}}_{\mathrm{SSIM}}$ for $\mathrm{PSNR}=30$ dB and $\mathrm{SSIM}=0.8$ with (orange) and without denoising (blue), respectively.
