Purpose

The module ExtendedConvolution implements some standard convolution filters like Average or Gauss whose kernel sizes can be specified by the user.

Optionally a threshold interval can be used to select a subset of voxels of the input image to which the filtering is applied. By using this interval filtering can be applied selectively to regions in the image and the number of filtered voxels can be reduced to gain performance.

Pad Dst Fill With Orig	PadDstFillWithOrig
Pad Src Undefined	PadSrcUndefined
Pad Dst Undefined	PadDstUndefined
Pad Src Clamp	PadSrcClamp

Fill Value

name: fillValue, type: Double, default: 0

Sets the fill value for certain Border Handling modes.

KernelX

name: kernelX, type: Integer, default: 3, minimum: 1, maximum: 999

Sets the x-extent of the kernel.

KernelY

name: kernelY, type: Integer, default: 3, minimum: 1, maximum: 999

Sets the y-extent of the kernel.

KernelZ

name: kernelZ, type: Integer, default: 1, minimum: 1, maximum: 999

Sets the z-extent of the kernel.

name: kernelC, type: Integer, default: 1, minimum: 1, maximum: 999

Sets the c-extent of the kernel.

KernelT

name: kernelT, type: Integer, default: 1, minimum: 1, maximum: 999

Sets the t-extent of the kernel.

KernelU

name: kernelU, type: Integer, default: 1, minimum: 1, maximum: 999

Sets the u-extent of the kernel.

Make kernel spherical

name: makeSpherical, type: Bool, default: FALSE

If checked, the used kernel is a spherical kernel, not a rectangular one.

Min (intervalMinOfFilteredVoxels)

name: intervalMinOfFilteredVoxels, type: Double, default: 0, deprecated name: imageIntervalMin

Sets the minimum value threshold for outputting a subset of voxel.

Max (intervalMaxOfFilteredVoxels)

name: intervalMaxOfFilteredVoxels, type: Double, default: 1024, deprecated name: imageIntervalMax

Sets the maximum value threshold for outputting a subset of voxel.

Use (useIntervalOfFilteredVoxels)

name: useIntervalOfFilteredVoxels, type: Bool, default: FALSE, deprecated name: useImageInterval

If checked, the module outputs only on a subset of voxels defined by a value range.

Min (intervalMinOfVoxelsForFiltering)

name: intervalMinOfVoxelsForFiltering, type: Double, default: 1, deprecated name: kernelIntervalMin

Sets the minimum value threshold for operating on a subset of voxel.

Max (intervalMaxOfVoxelsForFiltering)

name: intervalMaxOfVoxelsForFiltering, type: Double, default: 4095, deprecated name: kernelIntervalMax

Sets the maximum value threshold for operating on a subset of voxel.

Use (useIntervalOfVoxelsForFiltering)

name: useIntervalOfVoxelsForFiltering, type: Bool, default: FALSE, deprecated name: useKernelInterval

If checked, the module operates only on a subset of voxels defined by a value range.

Info

name: kernelInfo, type: String, persistent: no

Shows information about the used kernel.
