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 implementation is done separable. In case a sigma equals zero, the direction is not blurred.
DEPRECATED: This method is deprecated. Use gaussianBlur2D instead.
