Properties
View SourceMinKeyPointMatches
Gets or sets the minimum number of key points matches required for recognition.
Declaration
public int MinKeyPointMatches { get; set; }
Property Value
Type | Description |
---|---|
int | The minimal number of key points should be matched between an image and a scene for image objects recognition. The default is 30. |
Exceptions
Type | Condition |
---|---|
System.ObjectDisposedException | The ImageRecognitionConfiguration already has been disposed of. |
System.ArgumentOutOfRangeException |
|
RequiredMatchingPart
Gets or sets the required matching part for the image recognition. To recognize occluded or hidden an image by other images, required relative part of the matches in respect to the total amount of matching keypoints required for image recognition. Too low value will result in unsustainable behavior, but the effect of object overlapping will be reduced.
Declaration
public double RequiredMatchingPart { get; set; }
Property Value
Type | Description |
---|---|
double | The value indicating required relative part of the matches; can be from 0 to 1, inclusive. The default is 0.05. |
Exceptions
Type | Condition |
---|---|
System.ObjectDisposedException | The ImageRecognitionConfiguration already has been disposed of. |
System.ArgumentOutOfRangeException |
|
SceneMaxKeyPoints
Gets or sets the maximum key points that should be detected on the scene. The maximal number of key points can be selected on the scene including the images (objects) to calculate descriptors.
Declaration
public int SceneMaxKeyPoints { get; set; }
Property Value
Type | Description |
---|---|
int | The maximal key points for image recognition. The default is 5000. |
Exceptions
Type | Condition |
---|---|
System.ObjectDisposedException | The ImageRecognitionConfiguration already has been disposed of. |
System.ArgumentOutOfRangeException |
|
SceneScaleFactor
Gets or sets the scene scale factor.
Declaration
public double SceneScaleFactor { get; set; }
Property Value
Type | Description |
---|---|
double | The value indicating the factor will be used for resizing of the scene including the images (objects) for recognition. The default is 1.2. |
Exceptions
Type | Condition |
---|---|
System.ObjectDisposedException | The ImageRecognitionConfiguration already has been disposed of. |
TolerantPartMatchError
Gets or sets the part matching error for the image recognition.
Allowable error of matches number.
Declaration
public double TolerantPartMatchError { get; set; }
Property Value
Type | Description |
---|---|
double | The value indicating allowable error of matches; can be from 0 to 1, inclusive. The default is 0.1. |
Exceptions
Type | Condition |
