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.
	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.)
	CreateResultGraphics	Creates a composite result graphic containing child graphics specified by the GraphicOptions which is a bitwise combination of CogBlobResultGraphicConstants.
	Dispose	Destruct this CogBlobResult.
	Dispose(Boolean)
	Equals	Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
	Finalize	Finalize this CogBlobResult. (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.)
	GetBoundary	Creates a closed polygon representing the boundary of the blob which completely encloses all pixels that are part of this blob, regardless of the blob weight associated with each pixel. The boundary always falls directly between the edges of pixels.
	GetBoundingBox	Gets a bounding box of the blob that is aligned with the specified axis. The exclude extrema properties of the run parameters are used when calculating the bounding box, except when Axis is set to CogBlobAxisConstants::PixelAlignedNoExclude.
	GetBoundingBoxAtAngle	Gets a bounding box of the blob that is aligned with the specified angle. The exclude extrema properties of the run parameters are used when calculating the bounding box.
	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.)
	GetMeasure	Returns the value of the blob CogBlobMeasureConstants requested.
	GetMedianX	The x-coordinate of the point through which two orthogonal lines each divide the blob's area in half. The orthogonal lines are aligned with the Axis specified. MedianX is specified in units of the input image's selected space.
	GetMedianY	The y-coordinate of the point through which two orthogonal lines each divide the blob's area in half. The orthogonal lines are aligned with the Axis specified. MedianY is specified in units of the input image's selected space.
	GetObjectData	Implements the GetObjectData method of the ISerializable interface. (Inherited from CogSerializableObjectBase.)
	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.)
	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.)
	ToString	Returns a String that represents the current Object. (Inherited from Object.)

Properties

	Name	Description
	Acircularity	The acircularity of this blob as defined by the formula: perimeter^2 / (4 x Π x Area). This measure is not available when using whole-image connectivity.
	AcircularityRms	The acircularity of this blob as defined by the normalized RMS deviation of the boundary point radius values from r0, where r0 is the square root of the blob's area divided by Π. This measure is not available when using whole-image connectivity.
	Angle	The angle of the principal axis of the blob, specified in units of the input image's selected space at run-time.
	Area	The area of the blob specified in units of the input image's selected space at run-time. The area measure takes into account the blob weight of each pixel. Weighting is accomplished by assigning values between 0 and 255 to each pixel, then normalizing the total of the values of the pixels that make up the blob using the ScalingValue.
	CenterOfMassX	The x-coordinate of the center of mass of the blob specified in units of the input image's selected space at run-time.
	CenterOfMassY	The y-coordinate of the center of mass of the blob specified in units of the input image's selected space at run-time.
	Elongation	The ratio of InertiaMax to InertiaMin.
	FilteredOut	True if this blob was filtered out based on any of filter criteria specified in the RunTimeMeasures. False, otherwise.
	ID	A unique ID used to identify this blob within the context of the CogBlobResults object that contains this result.
	InertiaMax	The blob's second moment of inertia about the second principal axis of the blob.
	InertiaMin	The blob's second moment of inertia about the principal axis of the blob.
	InertiaX	The second moment of inertia of the blob about an axis drawn through the blob's center of mass and parallel to the Y-axis of selected space of the input image.
	InertiaY	The second moment of inertia of the blob about an axis drawn through the blob's center of mass and parallel to the X-axis of selected space of the input image.
	Label	The connectivity label. For grey scale connectivity, the label will be 1 for blobs and 0 for holes. For labeled connectivity, this is the blob's label.
	NotClipped	This measure will be 1.0 if the blob was not clipped during processing. It will be zero if the blob touches the edge of the region of interest, or the edge of the run-time image, or any Don't Care pixel in the InputImageMask.
	NumChildren	The number of children of this blob after all filter criteria are applied.
	NumUnfilteredChildren	The number of children of this blob before any filter criteria are applied.
	Perimeter	The perimeter of the blob specified in units of the input image's selected space at run-time. Formula corrects for the tendency of the pixel aligned boundary of the blob to overstate the true blob perimeter. Not available for whole-image connectivity.
	SelectedSpaceName	Returns the name of the selected space of the input image at run-time. All relevant blob measures are specified in units of the selected space.
