This paper focuses on a general framework for singular point extraction from vector field. We design a new index of singular point based on complex polynomial model. We test our method in the publicly available benchmark dataset of the singular point detection competition (SPD2010). Our algorithm gets the best results and produces large margins com...

... In the following, we shall give a thorough overview on detection methods. Singular point detection methods on the traditional digital image processing can be further divided into three subcategories, including the methods on the Poincare index [1,6,[13][14][15], the ones on filter and model techniques [8,[16][17][18][19] and the ones on the hybrid schemes [5,7]. The Poincare index of a point is defined as the cumulative orientation differences counterclockwise along a simple closed [1], and it can be used to judge whether there are singular points in an orientation field block or not. ...
