Edge Detection

Edge Detection by Canny-Deriche filtering

This plugin performs a Canny-Deriche filtering for edge detection. A parameter controls the degree of smoothing applied; the default value is 1.0, greater values imply less smoothing but more accurate detection, lower values imply more smoothing but less accurate detection. A non-maximal suppression is then performed to get thin edges. The angle of the edges can also be displayed.

A double thresholding by hysteresis is also included but can be found separately here.

It has been written originaly by Thomas Boudier and then repackaged by Joris Meys.

Download image_edge.jar to your plugins directory and then restart ImageJ or use the Update Menus command.

The source code is also available : imageedgesrc.jar (rename as .zip to unzip it).
