Hallucinating occlusions by filling superpixels with noise

[antoniopavlis]

Hi, congrats on your work ! In your work it is said that you "randomly select several superpixels and fill them with noise" to hallucinate occlusions. I wonder what aprox percentage of target image you cover with noise ? Approximately, in how many superpixels you divide image and how many of them you choose to add noise. Image shouldn't be covered with noise too much, am I right ?
