Parameters

Name	Description	Data Type	Required?
borderType	Pixel extrapolation method, see BorderTypes [Default: borderType = BORDER_DEFAULT]	string
image_array	Numpy Image Array	string
ksize	Gaussian kernel size. ksize.width and ksize.height can differ but they both must be positive and odd. Or, they can be zero's and then they are computed from sigma.	integer
sigmaX	Gaussian kernel standard deviation in X direction.	float
sigmaY	Gaussian kernel standard deviation in Y direction; if sigmaY is zero, it is set to be equal to sigmaX, if both sigmas are zeros, they are computed from ksize.width and ksize.height, respectively (see getGaussianKernel for details); to fully control the result regardless of possible future modifications of all this semantics, it is recommended to specify all of ksize, sigmaX, and sigmaY.	float
