Issue with Needle Detection #44

Open osleland opened 1 year ago

osleland commented 1 year ago

I've had a recurrent issue where OpenDrop doesn't recognize needle diameter. I've tried reselecting the needle with the needle select multiple times, including different regions, but it still shows a bluish shading around the needle without detecting it with the yellow line. As a result, most of my photos don't work. I've attached an example of the same image, one with the brightness adjusted to make the gray values more distinct, but neither will pick up the needle. Is there something I'm doing wrong?

Do you mind attaching your original image? Im wondering if the edge detection is failing because the edges are too blurred or if the image is noisy. Another thing you can try is downscaling the image if it's very high resolution.
