 | KeyPoint Structure |
Data structure for salient point detectors
Namespace: OpenCvSharp
Assembly: OpenCvSharp (in OpenCvSharp.dll) Version: 1.0.0
SyntaxThe KeyPoint type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | KeyPoint(Point2f, Single, Single, Single, Int32, Int32) |
Complete constructor
|
| KeyPoint(Single, Single, Single, Single, Single, Int32, Int32) |
Complete constructor

Methods| Name | Description | |
|---|---|---|
| Equals(Object) | Indicates whether this instance and a specified object are equal. (Overrides ValueTypeEquals(Object).) |
| Equals(KeyPoint) | Indicates whether the current object is equal to another object of the same type. |
| GetHashCode | Returns the hash code for this instance. (Overrides ValueTypeGetHashCode.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| ToString | Returns the fully qualified type name of this instance. (Overrides ValueTypeToString.) |
Operators| Name | Description | |
|---|---|---|
  | Equality |
Compares two CvPoint objects. The result specifies whether the members of each object are equal.
|
| Inequality |
Compares two CvPoint objects. The result specifies whether the members of each object are unequal.
|
Fields| Name | Description | |
|---|---|---|
 | Angle |
Feature orientation in degrees (has negative value if the orientation is not defined/not computed)
|
| ClassId |
Point class (can be used by feature classifiers or object detectors)
|
| Octave |
Scale-space octave in which the feature has been found; may correlate with the size
|
| Pt |
Coordinate of the point
|
| Response |
Feature strength (can be used to select only the most prominent key points)
|
| Size |
Feature size
