| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | This paper presents an exact maximum likelihood computation for fitting an ellipse to points in the image in the presence of high level noise, minimizing the sum of square orthogonal distances from the data to the fitted ellipse. This can be done by iteratively applying the known method for low level noise, and the computation is extremely simple as compared with existing methods to the same purpose. However, we show by experiments that the high-level noise method and the low level-noise method do not produce any meaningful differences in the resulting solution and that the known low level method is sufficient in practice. |
