#include <vpi/algo/GaussianFilter.h>

Runs a 2D Gaussian filter over an image.

Parameters

[in]	stream	The stream where the operation will be queued in.
[in]	backend	Backend that will execute the algorithm.
[in]	input	Input image to be filtered.
[out]	output	Image where the result will be written to.
[in]	kernelSizeX,kernelSizeY	Gaussian kernel size in X and Y directions respectively. If 0, it'll be 2*ceil(3*sigma) rounded to the next odd size. Limited between 3 and 11, and must be odd.
[in]	sigmaX,sigmaY	Standard deviation of the Gaussian kernel in the X and Y directions respectively. If kernelSize==0, sigma is limited to 2.
[in]	border	Border extension to be used.

Returns

an error code on failure else VPI_SUCCESS.
