3D Data Augmentation

For some processing and analysis purposes, you may want to create deformed or warped datasets. For example, to test invert problems such a non-rigid registration or to create additional data for deep model training. For these purposes, Dragonfly includes a 3D data augmentation generator that lets you create warped datasets from an original dataset.

Right-click the original dataset, region of interest, or multi-ROI and then choose 3D Data Augmentation in the pop-up menu to open the 3D Data Augmentation dialog, shown below.

3D Data Augmentation dialog

In the 3D Data Augmentation dialog, you can:

• Select the number of outputs required.

• Set the seed positions and vector magnitude distribution, as well as an image intensity interpolation.

• Choose to generate deformation vector fields, in addition to the generated datasets.
