Basic| Module: | OpenCV |
|---|
Returns Gaussian filter coefficients.
Applications
Prepares matrix to be used with cvSepFilter2D or cvFilter2D.
| Name | Type | Range | Description | |
|---|---|---|---|---|
 |
inKSize | Integer | 1 -  |
Aperture size. It should be odd and positive. |
|
inSigma | Real | Gaussian standard deviation. If it is non-positive, it is computed from ksize. | |
 |
outKernel | Matrix | Output Gaussian coefficients. | |
Errors
This filter can throw an exception to report error. Read how to deal with errors in Error Handling.
List of possible exceptions:
| Error type | Description |
|---|---|
| DomainError | inKSize must be odd in cvGetGaussianKernel. |
