These can be simply obtained using the Canny edge detector and picking a random set of points from the edges.

One main reason is to provide complementary information about regions, which is not obtained from edge detectors or corner detectors.

They apply an edge detector to extract edges from a range image.

These so-called simple cells were later called bar detectors or edge detectors.

Segmentation methods can also be applied to edges obtained from edge detectors.

The template and image are often pre-processed via an edge detector giving a binary image.

It was one of the first edge detectors and was initially proposed by Lawrence Roberts in 1963.

For this reason, many important image analysis tools such as edge detectors and neural networks are inspired by human visual perception models.

In terms of definitions, there is a close connection between edge detectors and ridge detectors.

If is large enough, then this becomes an edge detector.
