Hi,
I have a BW image containing large arcs. I was thinking of using imfindcircles to detect them, but their centers are certainly off the image because the radii are quite large. Any ideas on what would be the best way to detect these curves?

Can we see your image? Where did you upload it to?

That's really easy. Just binarize it if it's not already
binaryImage = grayImage > 255;
Then find the coordinates
[rows, columns] = find(binaryImage);
Then use the FAQ to fit to a circle:
