Abstract
Chen and Xie reported the development of a pen-based Fuzzy Freehand Drawing System (FFDS) that uses a Limiting multiplier to reconstruct ellipses from scattered data. The purpose of the present work is to show that although Chen and Xie's method is of interest, two of their equations (Eqs. 11 and 12) are correct only for a special case and not in general.
