Computes the Gaussian blurred image of an image given two sigma values in X and Y. Thus, the filterkernel can have non-isotropic shape.
The Gaussian blur is applied slice by slice in 2D.
DEPRECATED: This method is deprecated. Use gaussianBlur3D instead.
Ext.CLIJx_blurSliceBySlice(Image source, Image destination, Number sigmaX, Number sigmaY);
