Failure case 2. Noise2Atom is sensitive to gradients in background noise. In this image, at the edge of a nanodroplet with a low concentration of Pt atoms, there is an increase of background noise from left to right (shown in the plot below), as the nanodroplet gets thicker. On the left of the image where a small amount on atoms are correctly fit. However, further to the right of the image, as the background noise increases, clusters of pixels from the background noise, increasingly gets overfit as false atoms
