Table 1

Quantitative comparisons (PSNR/SSIM) of different methods over the PPM-100 dataset. Four images we show in Figure 10 were selected as examples to show individual results. The average values of PSNR/SSIM over the whole PPM-100 dataset are shown in the table as well.

Example	MODNet+RainNet		RainNet with GT alpha matte		Ours
	PSNR	SSIM	PSNR	SSIM	PSNR	SSIM
(a)	19.32	0.822	27.68	0.865	26.62	0.869
(b)	19.37	0.848	20.95	0.861	27.00	0.894
