public class DoGSIFTEngine
extends Object
implements Engine<Keypoint,FImage>

An implementation of Lowe's SIFT: specifically both the difference-of-Gaussian detector coupled with a SIFT descriptor.

This class and its sister options class DoGSIFTEngineOptions wrap all the work needed to extract SIFT features into a single place without having to deal with the setup of pyramid finders, collectors and providers.
