Ellipse Detection (for Aurora Oval Segmentation)

Illustration of our ellipse detection method that is based on least-squares fitting and randomized Hough transform (RHT). Here, we apply the work to Aurora Oval segmentation. An extension of the ellipse detection method to ellipsoid detection has also been studied. The ellipsoid detection method exploits geometric properties of ellipsoids in an evidence accumulation process also based on RHT.
