Syntax
The CogCaliperScorerPositionNormNeg type exposes the following members.
Constructors
| Name | Description | |
|---|---|---|
 | CogCaliperScorerPositionNormNeg | Constructs a new instance of this class. |
| CogCaliperScorerPositionNormNeg(IntPtr) | Constructs a new instance of this class using com pointer. |
| CogCaliperScorerPositionNormNeg(CogCaliperScorerPositionNormNeg) | Constructs a new instance of this class as a deep copy of the given instance. |
Methods
| Name | Description | |
|---|---|---|
 | Clone | Returns a deep copy of this class instance. Derived classes that implement Clone should override this method; other clients who wish to clone this instance should call ICloneable.Clone. See also CogSerializer.DeepCopyObject |
| CreateObjRef | Creates an object that contains all the relevant information required to generate a proxy used to communicate with a remote object. (Inherited from MarshalByRefObject.) |
| Dispose | |
| Dispose(Boolean) | |
| Equals | (Inherited from Object.) |
| Finalize | (Overrides Object Finalize .) |
| GetAttributes |
Implements the corresponding member of the ICustomTypeDescriptor interface.
May be overridden in derived classes to provide custom type information.
(Inherited from CogObjectBase.) |
| GetClassName |
Implements the corresponding member of the ICustomTypeDescriptor interface.
May be overridden in derived classes to provide custom type information.
(Inherited from CogObjectBase.) |
| GetComponentName |
Implements the corresponding member of the ICustomTypeDescriptor interface.
May be overridden in derived classes to provide custom type information.
(Inherited from CogObjectBase.) |
| GetConverter |
Implements the corresponding member of the ICustomTypeDescriptor interface.
May be overridden in derived classes to provide custom type information.
(Inherited from CogObjectBase.) |
| GetDefaultEvent |
Implements the corresponding member of the ICustomTypeDescriptor interface.
May be overridden in derived classes to provide custom type information.
(Inherited from CogObjectBase.) |
| GetDefaultProperty |
Implements the corresponding member of the ICustomTypeDescriptor interface.
May be overridden in derived classes to provide custom type information.
(Inherited from CogObjectBase.) |
| GetEditor |
Implements the corresponding member of the ICustomTypeDescriptor interface.
May be overridden in derived classes to provide custom type information.
(Inherited from CogObjectBase.) |
| GetEvents |
Implements the corresponding member of the ICustomTypeDescriptor interface.
May be overridden in derived classes to provide custom type information.
(Inherited from CogObjectBase.) |
| GetEvents( Attribute ) |
Implements the corresponding member of the ICustomTypeDescriptor interface.
May be overridden in derived classes to provide custom type information.
(Inherited from CogObjectBase.) |
| GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
| GetLifetimeService | Retrieves the current lifetime service object that controls the lifetime policy for this instance. (Inherited from MarshalByRefObject.) |
| GetObjectData | |
| GetProperties |
Implements the corresponding member of the ICustomTypeDescriptor interface.
May be overridden in derived classes to provide custom type information.
(Inherited from CogObjectBase.) |
| GetProperties( Attribute ) |
Implements the corresponding member of the ICustomTypeDescriptor interface.
May be overridden in derived classes to provide custom type information.
(Inherited from CogObjectBase.) |
| GetPropertyOwner |
Implements the corresponding member of the ICustomTypeDescriptor interface.
May be overridden in derived classes to provide custom type information.
(Inherited from CogObjectBase.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| GetXYParameters | Get the parameters used to map an edge pair candidate's position to a score. When mapping, the signed difference in position between the edge pair model origin and the center of the projection region is computed. This value is in turn divided by the expected width of the edge pair, yielding a normalized relative position value. Score is a unitless value in the range of 0.0 (no edge found) through 1.0 (edge found). |
| InitializeLifetimeService | Obtains a lifetime service object to control the lifetime policy for this instance. (Inherited from MarshalByRefObject.) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
| MemberwiseClone(Boolean) | Creates a shallow copy of the current MarshalByRefObject object. (Inherited from MarshalByRefObject.) |
| ResumeAndRaiseChangedEvent | Re-enables raising of the Changed event after SuspendChangedEvent has been called. Also raises the Changed event if the ChangedEventSuspended count is reduced to zero and any changes were made while events were suspended. Must be called once for each call to SuspendChangedEvent. |
| Scores | Whether this scorer applies for the given number of edges. |
| SetXYParameters | Set the parameters used to map an edge pair candidate's position to a score. When mapping, the signed difference in position between the edge pair model origin and the center of the projection region is computed. This value is in turn divided by the expected width of the edge pair, yielding a normalized relative position value. Score is a unitless value in the range of 0.0 (no edge found) through 1.0 (edge found). |
| SuspendChangedEvent | Temporarily suspends the raising of the Changed event. May be called more than once, and a corresponding call to ResumeAndRaiseChangedEvent must be made for each call to SuspendChangedEvent. |
| ToString | (Inherited from Object.) |
Fields
| Name | Description | |
|---|---|---|
  | SfEnabled | This bit will be set in the EventArgs of a Changed event every time the value returned by Enabled may have changed. |
| SfGetXYParameters | This bit will be set in the EventArgs of a Changed event every time the value returned by GetXYParameters may have changed. |
Properties
| Name | Description | |
|---|---|---|
 | ChangedEventSuspended | If nonzero, indicates that the raising of the Changed event has been suspended. This value is incremented when SuspendChangedEvent is called and decremented when ResumeAndRaiseChangedEvent is called. |
| Enabled | Whether this scorer will be used. |
| HasChanged | If true, the serializable state of this object has changed since the last time it was serialized. |
Events
| Name | Description | |
|---|---|---|
 | Changed | Occurs when one or more parts of the object's state may have changed. |
Remarks
A scoring function that uses the normalized position (positive or negative) of a candidate edge or edge pair. The position is normalized by dividing it by the expected distance between the edges (this function is only suitable if EdgeMode is CogCaliperEdgeModePair.
This is a one-sided scoring function object; you use SetXYParameters(Double, Double, Double, Double, Double) to set the individual values that define this function.
Unlike the CogCaliperScorerPositionNorm object, this object lets you score positive and negative values. In most cases, you will specify the XC, XO, and X1 values such that they enclose 0.0, as shown below:
