Parameters

hessianThreshold
Type: System..::..Single
The interest operator threshold. Use 100 for default
nOctaves
Type: System..::..Int32
The number of octaves to process. Use 4 for default
nIntervals
Type: System..::..Int32
The number of intervals in each octave. Use 4 for default
extended
Type: System..::..Boolean
True, if generate 128-len descriptors, false - 64-len descriptors. Use true for default.
featuresRatio
Type: System..::..Single
Max features = featuresRatio * img.size().srea(). Use 0.01 for default
upright
Type: System..::..Boolean
Use false for default. If set to true, the orientation is not computed for the keypoints
