Parameters

numberOfFeatures
Type: System..::..Int32
The number of desired features. Use 500 for default.
scaleFactor
Type: System..::..Single
Coefficient by which we divide the dimensions from one scale pyramid level to the next. Use 1.2f for default value
nLevels
Type: System..::..Int32
The number of levels in the scale pyramid. Use 8 for default value.
edgeThreshold
Type: System..::..Int32
How far from the boundary the points should be. Use 0 for default.
firstLevel
Type: System..::..Int32
The level at which the image is given. If 1, that means we will also look at the image.scaleFactor times bigger
WTK_A
Type: System..::..Int32
How many random points are used to produce each cell of the descriptor (2, 3, 4 ...). Use 2 for default.
scoreType
Type: Emgu.CV.Features2D..::..ORBDetector..::..ScoreType
Type of the score to use. Use Harris for default.
patchSize
Type: System..::..Int32
Patch size. Use 31 for default.
