Table 1.

Mean average and standard deviation (SD) of the PSNR for the simulated images without inpainting (no-inpainting) and the different inpainting methods with the original lesion mask (β₀) and Bonferroni-adjusted multi-comparison t-test of the PSNR results.

	Simulation (no-inpainting)	LWM	FSL	LEAP	NLM
Mean PSNR	20.25	20.89	22.46	21.75	23.52
SD	1.38	3.47	1.01	2.33	1.42
t-test with NLM [(t-value, df), p-value]	[(8.68, 27), < 0.01]	[(5.32, 27), < 0.01]	[(2.56, 27), 0.03]	[(5.43, 27), < 0.01]

The bold score represent the highest mean PSNR measure.
