Detailed Description

template<class TInputImage, class TOutputPointSet>
class otb::SiftFastImageFilter< TInputImage, TOutputPointSet >

This class extracts key points from an input image through a pyramidal decomposition.

This class implements the SIFT key point detector proposed by David G. Lowe in proceedings of International Conference on Computer Vision, Corfu, september 1999. The implementation used is provided by the external library libsiftfast (http://sourceforge.net/projects/libsift/), using the 1.2 release.

The code has been slightly modified in order to allow the user to tune the number of scales used in pyramidal decomposition.

Please note that OTB provides also a home-brewed version of the SIFT (ImageToSIFTKeyPointSetFilter).
