Member Function Documentation

virtual Mat DirectGraphicalModels::fex::CSIFT::get ( void  ) const
inlinevirtual

Extracts and returns the required feature.

Returns
The feature image.

Implements DirectGraphicalModels::fex::ILocalFeatureExtractor.

Definition at line 26 of file SIFT.h.

Here is the caller graph for this function:

Mat DirectGraphicalModels::fex::CSIFT::get ( const Mat &  img)
static

Extracts the SIFT feature.

For each pixel of the source image this function performs the scale-invariant feature transform.

Parameters
imgInput image of type CV_8UC1 or CV_8UC3.
Returns
Common feature extractor class with extracted SIFT feature of type CV_8UC{128}.
