public class SIFT_Detection_Demo
extends Object
implements PlugInFilter, JavaDocHelp

This plugin extracts multi-scale SIFT features [1] from the current image and displays them as M-shaped markers. The list of keypoints (if shown) is sorted by descending magnitude. The input image is always converted to grayscale before SIFT feature detection is performed. See Ch. 25 of [2] for details. If no image is currently open, the user is asked to load a predefined sample image.
