Abstract
AbstractConsider an Archimedean spiral in two-dimensional space series of points subject to random errors. In this paper, a methodology of a fitting procedure to spiral curve is studied. Three methods are proposed to give initial estimates of the spiral parameters. An Optimize algorithm proposed to updates the initial estimates. The approach is validated using simulated and real databases obtained from Parkinson patients handwriting. Finally, a comparison done between these three methods and Mishara’s method which shown that our methods give better results.
