11.50. ITK Maximum Projection Image Filter
Collapses a 3D volume to a 2D image by taking the maximum voxel value along one axis.
Group (Subgroup)
ITKImageStatistics (ImageStatistics)
Description
A projection collapses a 3D volume into a 2D image by combining all voxels along one axis into a single output value. This filter uses the maximum: for each line of voxels parallel to the selected axis, the output voxel is the largest value found along that line. The result has one fewer dimension than the input.
Maximum projection is the basis of the familiar maximum intensity projection (MIP) used to flatten bright features — vessels, particles, or other high-intensity structures — onto a single image regardless of their depth in the stack. Use it when you want to ensure the brightest object along each line of sight is preserved in the 2D summary.
Note
This filter changes the dimensionality of the Image Geometry that the data is tied to. As a side effect, every Data Array stored in the same Attribute Matrix as the input and output array is also affected.
Parameter Guidance
Projection Dimension — the axis to collapse, given as an index: 0, 1, or 2. Index 0 is the slowest-moving dimension. The output image keeps the two remaining axes.
Perform In-Place — when enabled, the projection replaces the input geometry rather than creating a new one.
Required Input Sources
Operates on any scalar image — typically from Read Image, Read Images [3D Stack], or the output of a prior ITK image filter.
