Table 5.

Comparison of superpixel and patch-based approach for the determination of necrotic and mucus area. Necrotic areas were present in all of the slides. However, only five slides contained mucus areas. Therefore, the average deviation for the relative mucus area is calculated once for all slides and once only for slides containing mucus.

Average deviation	Superpixel (%)	Patch-based (%)
Rel. necrotic area	1.77	1.22
Rel. mucus area (all WSIs)	0.19	0.24
Rel. mucus area (only WSIs containing mucus)	0.56	0.55
