/**
|
|
* Class for extracting Speeded Up Robust Features from an image CITE: Bay06 .
|
|
*
|
|
* The algorithm parameters:
|
|
* - member int extended
|
|
* - 0 means that the basic descriptors (64 elements each) shall be computed
|
|
* - 1 means that the extended descriptors (128 elements each) shall be computed
|
|
* - member int upright
|
|
* - 0 means that detector computes orientation of each feature.
|
|
* - 1 means that the orientation is not computed (which is much, much faster). For example,
|
|
* if you match images from a stereo pair, or do image stitching, the matched features
|
|
* likely have very similar angles, and you can speed up feature extraction by setting
|
|
* upright=1.
|
|
* - member double hessianThreshold
|
|
* Threshold for the keypoint detector. Only features, whose hessian is larger than
|
|
* hessianThreshold are retained by the detector. Therefore, the larger the value, the less
|
|
* keypoints you will get. A good default value could be from 300 to 500, depending from the
|
|
* image contrast.
|
|
* - member int nOctaves
|
|
* The number of a gaussian pyramid octaves that the detector uses. It is set to 4 by default.
|
|
* If you want to get very large features, use the larger value. If you want just small
|
|
* features, decrease it.
|
|
* - member int nOctaveLayers
|
|
* The number of images within each octave of a gaussian pyramid. It is set to 2 by default.
|
|
* NOTE:
|
|
* - An example using the SURF feature detector can be found at
|
|
* opencv_source_code/samples/cpp/generic_descriptor_match.cpp
|
|
* - Another example using the SURF feature detector, extractor and matcher can be found at
|
|
* opencv_source_code/samples/cpp/matcher_simple.cpp
|
|
*
|
|
* Member of `Xfeatures2d`
