JointHistogramMask

MLModule

genre	Histogram

package	MeVisLab/Standard

definition	MLJointHist.def
keywords	2D

Purpose

The module JointHistogramMask generates a binary mask using a selected region from a 2D histogram or an RGBA mask using a 2D RGBA LUT.

The 2D LUT is provided as a third input image, and the 2D histogram is computed internally.

Details

Example 1

As an example, we use simulated T1- and T2-weighted MR images. The images were obtained from the BrainWeb MR simulator.

T1-weighted image:

T2-weighted image:

2D-Histogram with a selected region:

Resulting images (T1-weighted with overlays):

Mask image 1:

Mask image 2:

Joint mask:

Example 2

This example use a gray image, a distance image, and a 2D-LUT to compute a mask.

Grey image:

Distance image:

2D-LUT (gray, distance):

Resulting mask:

Input Fields

The module requires two grey images with the same extent and a 2D LUT.

input0

name: input0, type: Image

Gray value image.

input1

name: input1, type: Image

Gray value image.

input2

name: input2, type: Image

2D-LUT.

Output Fields

output0

name: output0, type: Image

RGBA image with the same extent as the first two input images.

Visible Fields

Use rectangle

name: useRect, type: Bool, default: FALSE, deprecated name: useRectFld

If checked, the mask is calculated on base of a selected region in a 2D histogram.

Use 2D-LUT

name: useLut, type: Bool, default: TRUE, deprecated name: useLutFld

If checked, the mask is calculated on base of the entire attached 2D LUT.

Start World Pos. Of Rectangle

name: rectCoordP0, type: Vector3, default: 0 0 0, deprecated name: rectKoordP0Fld

Sets the start position of the rectangle selection in the 2D LUT.

End World Pos. Of Rectangle

name: rectCoordP1, type: Vector3, default: 0 0 0, deprecated name: rectKoordP1Fld

Sets the end position of the rectangle selection in the 2D LUT.
