Improved Entropic Edge-Detection

Using the Jensen-Shannon divergence of grey level histograms obtained by sliding a double window over an image, an edge-detector is presented. A new technique for linking unconnected edge points, based on estimated directions, is also described. The method is suitable for textured images and has proved to be fairly robust in the presence of impulsive noise or spurious patterns. An application to images of Diesel spray injection is shown, that may be used to improve combustion in Diesel motors.
