SoLocalAdaptiveThresholdProcessing engine
The SoLocalAdaptiveThresholdProcessing engine performs a binarization of a grayscale image based on the mean intensity of a sliding window centered around each voxel.
Each voxel value is compared to the mean intensity of its local window. The corresponding voxel in the binary output depends on the threshold value, mode, and comparison criterion.
In additive mode with comparison criterion set to GREATER_OR_EQUAL, the output is set to 1 if .
In multiplicative mode with comparison criterion set to GREATER_OR_EQUAL, the output is set to 1 if .
For example to select voxels lower than 90% of their local mean, set threshold field to 0.9, comparisonCriterion field to LESS_OR_EQUAL and thresholdMode field to MULTIPLICATIVE.
