Parameters
- pDst
- Pointer to the destination vector.
- kernelSize
- Size of the Sobel kernel.
- dx
- Order of derivative.
- sign
- Specifies signs of kernel elements.
Description
This function computes the one-dimensional Sobel kernel. Kernel coefficients are equal to coefficients of the polynomial
If the
sign
parameter is negative, then signs of kernel coefficients are changed. Kernel calculated by this function can be used to filter images by a high order Sobel filter.Return Values
- ippStsNoErr
- Indicates no error. Any other value indicates an error or a warning.
- ippStsNullPtrErr
- Indicates an error condition if thepDstpointer isNULL.
- ippStsSizeErr
- Indicates an error condition ifkernelSizeis less than 3 or is even.
- ippStsBadArgErr
- Indicates an error condition ifdxis equal to or less thankernelSize, ordxis negative.
