A direction based novel edge detector
Liming Zhang · 2006
Abstract:- This paper presents a novel direction based edge detector which not only can detect the whole edges in an image like other edge detectors, but also more effectively detect edges in any directions that are pre-selected by users. It provides users with an additional function to extract pieces of edges of the directions of particular interest. The algorithm is described in details. Effectiveness of the proposed edge detector is evaluated by comparing it with the Canny edge detector. The results are found to be promising.
