Residual Artifacts Detection

🎭 Created Masks

1. 📍 Coverage Mask (per-pixel)

   Binary per-pixel mask of detected artifacts. Note that the produced masks are downsampled compared to the original WSI.

   🏷️ Pixel values semantics

   The computed binary masks are scaled into the \([0, 255]\) range to allow for easier visualization. Therefore, the pixel values have the following semantics:

   • \(0\hphantom{55} \rightarrow\) No Artifact
   • \(255 \rightarrow\) Artifact

   However, due to downsampling of the created masks using local mean, it is safer to assume that any non-zero value indicates an artifact.

2. 🧱 Coverage Heatmap (per-tile)

   Mask indicating the fraction of each tile’s foreground area covered by artifacts. Note that the produced masks are downsampled compared to the original WSI. Originally, the masks contain floating point values from the \([0.0, 1.0]\) range. These values are then scaled into the \([0, 255]\) range.

   🏷️ Pixel values semantics

   • \(0\hphantom{55} \rightarrow\) No artifacts in the foreground
   • \(255 \rightarrow\) The entire foreground is an artifact
