ConvolveSep2D, ConvolveSep2DFP
Convolves an image with a
separable convolution kernel.
void iplConvolveSep2D (IplImage* srcImage ,
IplImage*
dstImage , IplConvKernel* xKernel ,
IplConvKernel* yKernel );
void iplConvolveSep2DFP (IplImage*
srcImage ,
IplImage*
dstImage , IplConvKernelFP* xKernel ,
IplConvKernelFP* yKernel );
srcImage Thesourceimage.
dstImage The resultant image.
xKernel The x or row kernel. Must contain only one row.
yKernel The y or column kernel. Must contain only one column.
Discussion
The functions iplConvolveSep2D() and iplConvolveSep2DFP() are
used to convolve the input image
srcImage with the separable kernel
specified by the row kernel
xKernel and column kernel yKernel .The
functions write the convolution results to the output image
dstImage .
Use
iplConvolveSep2DFP() only for images with 32-bit floating-point
data. For all other image data types, use
iplConvolveSep2D().
One of the kernel arguments
xKernel or yKernel (but not both) can be
NULL, for example:
iplConvolveSep2DFP (src, dst, xKernel, NULL);
iplConvolveSep2DFP (src, dst, NULL, yKernel);
