public class SoGaussianDerivativeProcessing
extends SoImageVizEngine

SoGaussianDerivativeProcessing image filter SoGaussianDerivativeProcessing approximates the convolution of an image with a Gaussian kernel or the derivative of a Gaussian kernel.

The filter is based on the recursive filtering method proposed by R.Deriche in IEEE-PAMI Vol.12, No.1, January 1990, pp 78-87, "Fast Algorithms for Low-Level Vision". Note that this filter has an infinite impulse response and takes advantage of the separability of the Gaussian kernel. Using this mode, the computation time is independent of the standard deviation.

File format/default:

GaussianDerivativeProcessing {

computeMode	MODE_AUTO
inImage	NULL
standardDeviation	1.0f 1.0f 1.0f
orderDerivative	0 0 0
