Subpixel Ellipse Detection Based on Hough Transform
Chen Li, Peng Wan, Tao He, Tielin Shi · Journal of Hubei Polytechnic University · 2005
In this paper, a subpixel ellipse detection method based on Hough transform is proposed. Here we reduce the parameters to a very small range by ellipse matching, and then use Hough transform to realize subpixel ellipse detection.
