Slide quantifications (annotations ?) are usually

Performed manually ❢ ① ✘ ✐ Performed within tissue subregions in small sample groups Created by isolated experts Stored locally (generally no backups) Proprietary formats

Hardly repeatable

Multi-gigapixel images

  • 15 x 15 mm
  • ≅ 0, 20µm/px
  • 100K x 100K pixels
  • +100Mb → +100Gb
  • pyramidal structure
