Canny Edge Detector

Canny Edge Detector. However, usually there will still be noise in the array E[i, j], i.e., non-zero values that do not correspond to any edge in the original image. In most cases, these values will be smaller than those indicating actual edges.

Weighted Graphs

Weighted Graphs. In a weighted graph, each edge has an associated numerical value, called the weight of the edge Edge weights may represent, distances, costs, etc. Example: In a flight route graph, the weight of an edge represents the distance in miles between the endpoint airports. 849.
