9.13. ITK Binary Projection Image Filter

Binary projection.

Group (Subgroup)

ITKImageStatistics (ImageStatistics)

Description

Image projection is a very common task in image analysis to reduce the dimension of an image. A base filter is provided with some specialized filters which implement different projection methods.

This class was contributed to the Insight Journal by Gaetan Lehmann. The original paper can be found at https://www.insight-journal.org/browse/publication/71

IMPORTANT NOTE

This filter will change the dimensionality of the Image Geometry that the data is tied to. This has the side effect of also changing every Data Array that is store in the same AttributeMatrix as the input and output data array.

Input Parameter(s)

Parameter Name	Parameter Type	Parameter Notes	Description
Projection Dimension	Scalar Value	UInt32	The dimension index to project. 0=Slowest moving dimension.
Perform In-Place	Bool		Performs the projection in-place for the given Image Geometry
Foreground Value	Scalar Value	Float64	Set the value in the image to consider as ‘foreground’. Defaults to maximum value of PixelType. Subclasses may alias this to DilateValue or ErodeValue.
Background Value	Scalar Value	Float64	Set the value used as ‘background’. Any pixel value which is not DilateValue is considered background. BackgroundValue is used for defining boundary conditions. Defaults to NumericTraits::NonpositiveMin() .

Input Cell Data

Parameter Name	Parameter Type	Parameter Notes	Description
Image Geometry	Geometry Selection	Image	Select the Image Geometry Group from the DataStructure.
Input Cell Data	Array Selection	Allowed Types: int8, uint8, int16, uint16, int32, uint32, int64, uint64, float32, float64	The image data that will be processed by this filter.

Output Data

Parameter Name	Parameter Type	Parameter Notes	Description
Created Image Geometry	String		The name of the projected geometry
Output Image Data Array	DataObjectName		The result of the processing will be stored in this Data Array.
