 MemberDescription
SURFDetector(Double, Boolean)
Create a MCvSURFParams using the specific values
ComputeDescriptors(Image<(Of <<'(Gray, Byte>)>>), array<MKeyPoint>[]()[][])
Compute the ImageFeature on the image from the given keypoint locations.
ComputeDescriptors(Image<(Of <<'(Gray, Byte>)>>), Image<(Of <<'(Gray, Byte>)>>), array<MKeyPoint>[]()[][])
Compute the descriptor given the image and the point location
DetectFeatures(Image<(Of <<'(Gray, Byte>)>>), Image<(Of <<'(Gray, Byte>)>>))
Detect image features from the given image
DetectKeyPoints(Image<(Of <<'(Gray, Byte>)>>))
Detect the keypoints in the image
DetectKeyPoints(Image<(Of <<'(Gray, Byte>)>>), Image<(Of <<'(Gray, Byte>)>>))
Detect the SURF keypoints from the image
Equals(Object)
Indicates whether this instance and a specified object are equal.
(Inherited from ValueType.)
extended
0 means basic descriptors (64 elements each), 1 means extended descriptors (128 elements each)
Finalize()()()()
Allows an Object to attempt to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection.
(Inherited from Object.)
GetHashCode()()()()
Returns the hash code for this instance.
(Inherited from ValueType.)
GetType()()()()
Gets the Type of the current instance.
(Inherited from Object.)
hessianThreshold
Only features with keypoint.hessian larger than that are extracted. good default value is ~300-500 (can depend on the average local contrast and sharpness of the image). user can further filter out some features based on their hessian values and other characteristics
MemberwiseClone()()()()
Creates a shallow copy of the current Object.
(Inherited from Object.)
nOctaveLayers
The number of layers within each octave (4 by default)
nOctaves
The number of octaves to be used for extraction. With each next octave the feature size is doubled (3 by default)
ToString()()()()
Returns the fully qualified type name of this instance.
(Inherited from ValueType.)
