Detailed Description

SoFloodFillThresholdProcessing engine

The SoFloodFillThresholdProcessing engine transforms a grayscale image into a binary image performing a region growing from a seed.

For an introduction, see section Binarization.

The SoFloodFillThresholdProcessing engine performs a so-called region growing either in 2D or in 3D. Starting from a voxel seed the algorithm selects the largest connected area that contains the voxel itself and all voxels with gray values lying inside the input range. The input range is specified via the inputRange field.

Notes:

• Compute mode.
  It is not really useful to apply this engine to a volume data set when computeMode is set to MODE_2D. In this case the algorithm will only affect the slice that contains the seedPoint Z value.
