Approximate Maximum-Likelihood Estimation Of Circle Parameters Using A Phase-Coded Kernel
Zelniker, Emanuel; Clarkson, Ian Vaughan L. - 2004
The accurate fitting of a circle to noisy measurements of points on its circumference is an important and much-studied problem in statistics. Atherton & Kerbyson (Image and Vision Computing 17, 1999, 795-803) have proposed a complex convolutional circle parameter estimator. One of the estimators...
