Multi-Path Dilated Residual Network for Nuclei Segmentation and Detection

. 2019 May 23;8(5):499. doi: 10.3390/cells8050499

Algorithm 1 AJI computation

Require: A series of images containing real annotations and predictive segmentation results;

G_{i}

is indexed by i for each real nucleus; Each prediction segmentation result

S_{k}

is indexed by k;
Ensure: AJI Score
1: Initialize the number of intersections and union between the real labeled area and the predicted segmentation result area, and count them
2:

C \leftarrow 0, U \leftarrow 0

3: for all

G_{i}

do
4:

j \leftarrow a r g m a x_{k} (| G_{i} \cap S_{k} | / | G_{i} \cup S_{k} |)

5: Refresh the counting:

C \leftarrow C + | G_{i} \cap S_{j} |, U \leftarrow U + | G_{i} \cup S_{j} |

6: Mark

G_{i}

8: for all

S_{i}

do
9:

j \leftarrow a r g m a x_{k} (| G_{i} \cap S_{k} | / | G_{i} \cup S_{k} |)

10: Refresh the counting:

C \leftarrow C + | G_{i} \cap S_{j} |, U \leftarrow U + | G_{i} \cup S_{j} |

11: Mark
