 === MVTec AD
 MVTec AD is a dataset for benchmarking anomaly detection methods with a focus on industrial inspection.
-It contains over 5000 high-resolution images divided into fifteen different object and texture categories.
+It contains 5354 high-resolution images divided into fifteen different object and texture categories.
 Each category comprises a set of defect-free training images and a test set of images with various kinds of defects as well as images without defects.

-Todo: descibe which categories are used in this bac and how many samples there are.
+In this bachelor thesis only two categories are used. The categories are "Bottle" and "Cable".
+
+The bottle category contains of 3 different defect classes: 'broken_large', 'broken_small' and 'contamination'.
+#subpar.grid(
+  figure(image("rsc/mvtec/bottle/broken_large_example.png"), caption: [
+    Broken large defect
+  ]), <a>,
+  figure(image("rsc/mvtec/bottle/broken_small_example.png"), caption: [
+    Broken small defect
+  ]), <b>,

+    Contamination defect
+  ]), <c>,
+  columns: (1fr, 1fr, 1fr),
+  caption: [Bottle category different defect classes],
+  label: <full>,
+)
+
+Whereas cable has a lot more defect classes: 'bent_wire', 'cable_swap', 'combined', 'cut_inner_insulation',
+'cut_outer_insulation', 'missing_cable', 'missing_wire', 'poke_insulation'.
+So many more defect classes are already an indication that a classification task will be more difficult for the cable category.
