How can I fill the scratch after scratch detection?

Hi, I'm struggling on how to fill the scratch after scratch detection. The mask of scratch detection is shown below.

After this, I'm trying to restore(remove) these scratches with interpolated value from neighbors, is there any way that I can interpolate the value?

Without knowing the original image content, you can probably do inpainting with regionfill()

If you have an older version, you can use inpaint_nans from the FEX:

Depending on the complexity of the image and the relative size of the defects, a more complex approach may work (R2019b+)
