Best Elliptical Fit for irregular shapes in an image <p>I have an image with arbitrary regions shape (say objects), let's assume the background pixels are labeled as zeros whereas any object has a unique label (pixels of object 1 are labeled as 1, object 2 pixels are labeled as 2,...). Now for every object, I need to find the best elliptical fit of its pixels. This requires finding the center of the object, the major and minor axis, and the rotation angle. How can I find these?</p> <p>Thank you;</p>
