I am trying to make MATLAB recognize ellipse in the image, but no matter how I adjust the thresholds for imbinarize and imadjust, MATLAB cannot fully recognize it. Are there any other methods I can try?

You can experiment with image filter or adjustment, followed by thresholding, and then proceed with a series of morphological steps. The precise steps for segmentation can be provided once I tried the initial process.
