Detailed Description

SoRecursiveLaplacianProcessing engine applies a recursive algorithm for the determination of the laplacian.

For an introduction, see:

• section Images Filters
• section Edge Detection
• Introduction to Laplacian

This engine is the recursive algorithm for the determination of the laplacian.

To minimize the effect of noise, the SoRecursiveLaplacianProcessing2d engine smooths the image before computing the laplacian. The smoothing scale parameter determines the smoothing intensity. If the value is large, the noise will be reduced but edges will be less sharp and only the most important edges will appear in the output image. It is important to select the right coefficient which will lower the noise just enough without defocusing the edges.
