SoGradientLocalMaximaProcessing3d engine. The SoGradientLocalMaximaProcessing3d engine suppresses the non-local maxima of the gradient amplitude.
For an introduction, see:
- section Edge Detection
- Introduction to Edge Marking
The Gradient Local Maxima engine suppresses the non-local maxima of the gradient amplitude. For each pixel of gradient image, gray level values within the neighborhood in the direction of the gradient are computed (given by X, Y and Z gradients). If this value is greater than all of its neighbors, it is kept, otherwise it is set to 0. This module eliminates some noise effects. It is very useful after applying the module SoGradientOperatorProcessing3d. The output edges are one pixel thickness edges. It is then possible to perform a SoHysteresisThresholdingProcessing.
