Abstract
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 accuracy of the 
edge points.
