I'd like to unite the curve segments of the binary image below to one single curve. Does anyone know, how to do this?

Best Answer

I = imread('img_curvesegments.jpg') ;
I1 = imbinarize(I);  
[y,x] = find(~I1) ;   
 [z, a, b, alpha] = fitellipse([x y])   
imshow(I1)
hold on
plot(x,y,'.r')
plotellipse(z,a,b,alpha)
