MinKeyPointMatches

Gets or sets the minimum number of key points matches required for recognition.

Declaration


                C#
                
                    Copy
                    
                
            
public int MinKeyPointMatches { get; set; }

Property Value

Type	Description
System.Int32	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
ObjectDisposedException	The ImageRecognitionConfiguration already has been disposed of.
System.ArgumentOutOfRangeException	`value` is less than zero.

API Level: 4

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

                    Copy
                    
                
            
public double RequiredMatchingPart { get; set; }

Property Value

Type	Description
System.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
ObjectDisposedException	The ImageRecognitionConfiguration already has been disposed of.
System.ArgumentOutOfRangeException	`value` is less than zero. -or- `value` is greater than one.
