-> SURF 

Parameters

hessianThreshold

Type: SystemDouble
Only features with keypoint.hessian larger than that are extracted.

nOctaves (Optional)

Type: SystemInt32
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.

nOctaveLayers (Optional)

Type: SystemInt32
The number of images within each octave of a gaussian pyramid. It is set to 2 by default.

extended (Optional)

Type: SystemBoolean
false means basic descriptors (64 elements each), true means extended descriptors (128 elements each)

upright (Optional)

Type: SystemBoolean
false means that detector computes orientation of each feature. true means that the orientation is not computed (which is much, much faster).
