Detailed Description

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

This class extracts key points from an input image, trough 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.

Input image is downsample by factor 2
Pyramid of gaussians is obtained by filtering input image with variable length sigma, each separated by a constant k = 2^(1/S) where S is the number of scales
Difference of gaussian are compute with the difference of two adjacent gaussian image results
Detector is laucnched on each difference of gaussian to find key point
A key point is a local minimum or a local maximum on 3*3 neighborhood
An interpolated location of the maximum key point is compute with fitting a 3D quadratic function
DoG low contrast are discarded (DoG < 3%)
High edge responses key point are discarded

Selected key points are stored in a itk::PointSet structure. Data points contains a list of (magnitude, main orientation) for each level of the pyramidal decomposition.

Orientation is expressed in degree in the range [0, 360] with a precision of 10 degrees.

Examples: Patented/SIFTExample.cxx.
