Image artifact removal applied to all images from BBBC021 dataset of MCF-7 cells [12]. Example of a contrast adjusted (a) and unadjusted (b) original image with noise artifact. The artifact consists of bright pixels oriented along 7 evenly spaced parallel lines with slope of ~ 0.1 (the arrows indicate one such line). The same image, with artifact removal applied as described in main text, shown with contrast adjusted (c) and unadjusted (d). Scale bar is 10 μm or 30 pixels. Artifact is best viewed in digital form
