Figure 1: Examples of different types of OOF. (a) Examples of different types of OOF: “global” affecting the whole slide, “regional” affecting a large expanse on a slide, and “local” affecting small tissue or cellular areas. (b) Example of the OOF scan lane in the regional OOF above (middle), that causes a striking artifact in a leading cancer detection algorithm. Left: the heatmap visualization of cancer predictions; black indicates nontissue-containing regions; and other colors range from blue (nontumor) to red (tumor). The OOF scan lane is predicted to be nontumor. Right: a zoom in of the OOF scan lane boundary. OOF: Out-of-focus
