Fitting Concentric Elliptical Shapes Under General Model
Ali Al-Sharadqah, Giulano Piga
The problem of fitting concentric ellipses is a vital problem in image processing, pattern recognition, and astronomy. Several methods have been developed but all address very spec…
New Methods for Detecting Concentric Objects With High Accuracy
Ali A. Al-Sharadqah, Lorenzo Rull
Fitting concentric geometric objects to digitized data is an important problem in many areas such as iris detection, autonomous navigation, and industrial robotics operations. Ther…
A simple approach to construct confidence bands for a regression function with incomplete data
Ali Al-Sharadqah, Majid Mojirsheibani
A long-standing problem in the construction of asymptotically correct confidence bands for a regression function , where is the response variable influenced by t…
Error analysis for circle fitting algorithms
A. Al-Sharadqah, N. Chernov
We study the problem of fitting circles (or circular arcs) to data points observed with errors in both variables. A detailed error analysis for all popular circle fitting methods -…
