3 years ago Hi, bugua, you need to remove some unrelated edge segments after the edge detection. Could you please let me see your images, i.e., eye.png. Maybe I could find something.
Best and sincere wishes, Mingyang

I try like this but the result emmm
f=imread('eye.png'); g=im2bw(f,graythresh(f));%图像二值化 g = edge(g); [r, c] = find(g == 1); rc = [r c]; figure plot(rc(:,1),rc(:,2),'k.'); axis equal; title('Input data points'); %parameter setting N=50; R=10; %start ellipse fitting by HGMM [FittedEllipse]=HGMM_fit(rc,N,R); figure plot(rc(:,1),rc(:,2),'k.'); axis equal; hold on; title("HGMM-ellipse fitting"); [,,tx,ty]=gen_elp([FittedEllipse 0 60 0]); plot(tx',ty','r-','Linewidth',2);
