ALTDoGSIFTEngine
SIFT engine that isn't rotation invariant (using 
  
NullOrientationExtractor) and uses the 
 IrregularBinningSIFTFeatureProvider. | 
class  | 
BasicGridSIFTEngine
Really basic SIFT extraction on a regular grid of interest points. 
 | 
class  | 
DoGColourSIFTEngine
The  
DoGSIFTEngine extended to colour images (aka Colour-SIFT). | 
class  | 
DoGSIFTEngine
 An implementation of Lowe's SIFT: specifically both the
 difference-of-Gaussian detector coupled with a SIFT descriptor. 
 | 
class  | 
MinMaxDoGSIFTEngine
A modified implementation of Lowe's difference-of-Gaussian detector and SIFT
 feature extraction technique that also records whether features are detected
 at local minima or maxima by looking at the sign of the difference of
 Gaussian.
