We compare various methods in (a)–(f). (a) Original H&E image ${\mathcal{I}}_0$, (b) annotation image $\mathcal{G}$, (c) image ${\mathcal{S}}^{\text{pixel}}$ by our method, (d) image ${\mathcal{S}}^{\mathrm{Nguyen}}$ by Nguyen et al.,²³ (e) image ${\mathcal{S}}^{\mathrm{Naik}}$ by Naik et al.,¹⁷ and (f) image ${\mathcal{S}}^{\mathrm{Farjam}}$ by Farjam et al.¹⁶ We also illustrate a failure case for our method in (g)–(i). (g) Another input H&E image, (h) corresponding annotation image, overlaid on image in (g), and (i) our result ${\mathcal{S}}^{\text{pixel}}$. All the annotation/segmented images are shown overlaid on the corresponding original image ${\mathcal{I}}_0$ and red: gland, blue: lumen, green: periacinar retraction clefting, and white: stroma.
