The Gradient Amplification module is a new class for sliceOmatic 5.0. This class enable you to artificially increase the gradient around a specific target GLI value. This will help segmentation techniques that are gradient based (such as "Morpho" and "Snake"). It can be used for example in segmenting CT images where you know you want to segment at specific Hounsfield values but do not want to use threshold based techniques. By increasing the gradient at the desired Hounsfield value, you insure that the gradient based technique will find the correct boundary.
The Gradient Amplification class is enabled through the 2D Mode: "DB Class management" interface. Once you have a mixer in your database tree, a new "Gradient" button will be present in the Modes menu. This button will open the gradient amplification's interface.

The GLI Computation
Using the notation:
Depending on the value of ∆, there are 4 possibilities when computing the new GLI value X':
