Abstract
We present a filtering method for 2D curvilinear structures, called 
RORPO (Ranking the Orientation Responses of Path Operators). RORPO is 
based on path operators, a recently developed family of mathematical 
morphology filters. Compared with state of the art methods, RORPO is 
non-local and well adapted to the intrinsic anisotropy of curvilinear 
structures. Since RORPO does not depend on a linear scale-space 
framework, it tends to preserve object contours without a blurring 
effect. Due to these properties, RORPO is a useful low-level filter and 
can also serve as a curvilinear prior in segmentation frameworks. In 
this article, after introducing RORPO, we develop the 2D version of the 
algorithm and present a few applications.
