Once we have computed a measure of edge strength ( typically the gradient magnitude ), the next stage is to apply a threshold, to decide whether edges are present or not at an image point.

Once we have a start point, we then trace the path of the edge through the image pixel by pixel, marking an edge whenever we are above the lower threshold.
