| Member | Description | |
|---|---|---|
| MCvSURFParams(Double, Boolean) |
Create a MCvSURFParams using the specific values
|
| 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>)>), 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.) |
