Research on the Segmentation of Biomarker for Chronic Central Serous Chorioretinopathy Based on Multimodal Fundus Image

Pseudocode 1

The pseudocode.

Input:S_P, K, K₁, K₂, I_a, T;

  Ford =1:K

   Calculate the coordinate of seed point (, ) by Eq. (8);

   Set the initial value of =0;

   Set the initial value of pixelnumber Pn =1;

   Set the number of neighborhoods Nd =4;

   Set the initial average gray value of the segmented region Ra = I_a (, );

   WhilePnK₁ × K₂.

    1: Calculate the value of each pixel in the neighborhood of the current seed point (, ) by if ,add these pixels into R_Pd;

    2: Calculate the average gray value Ra of the current segmentation region R_Pd;

    3: Pn = Pn++; Update the seed point (, );

   End.

 End.

 Calculate F_S by Eq. (10).
