Gaussian Blur
Description
Blurs an image using a Gaussian filter. The function convolves the source image with the specified Gaussian kernel. Type : polymorphic.
Input parameters
Image Src : class, type accepted U8, I16, RGB and HSL. ROI : class, if ROI is wired we apply blur only on ROI pixel different of 0 (type accepted U8, I16, RGB and HSL).
Gaussian Blur Parameters : cluster,
ksize_x : integer, gaussian kernel width. ksize_y : integer, gaussian kernel height.
sigma_x : float, gaussian kernel standard deviation in X direction. sigma_y : float, gaussian kernel standard deviation in Y direction.
ksize_x and ksize_y can differ but they both must be positive and odd. Or, they can be zero’s and then they are computed from sigma.
If sigma_y is zero, it is set to be equal to sigma_x, if both sigmas are zeros, they are computed from ksize_x and ksize_y, respectively to fully control the result regardless of possible future modifications of all this semantics, it is recommended to specify all of ksize_x, ksize_y, sigma_x, and sigma_y.
Output parameters
Image Dst : class
