A curvature-based edge detector for x-ray radiographs

Radiographs have been a great asset for radiologists in detecting diseases and bone fractures, however they are especially difficult for computer vision systems to analyze. One major difficulty is the lack of ability to use low-level features such as edges. Current edge detectors are unable to give continuous edges around object boundaries without any gaps. In this paper, we propose a method for detecting edges in x-ray radiographs which gives more continuous edges around object boundaries than the most commonly used edge detector while still eliminating many false edges.
