A sub-pixel edge detector: an implementation of the Canny/Devernay Algorithm

An image edge detector is described which produces chained edge points with sub-pixel accuracy. The method incorporates the main ideas of the classic Canny and Devernay algorithms. The analysis shows that a slight modification to the original formulation improves the sub-pixel accuracy of the edge p...

Sumario:An image edge detector is described which produces chained edge points with sub-pixel accuracy. The method incorporates the main ideas of the classic Canny and Devernay algorithms. The analysis shows that a slight modification to the original formulation improves the sub-pixel accuracy of the edge points.
