| divisor | An integer value by which a result is divided. | |
| dstRoiSize | Destination image ROI size. | |
| dstStep | Destination buffer step size (width of the buffer in bytes). | |
| kernelSize | Specifies the size of the kernel used in calculations. | |
| pDst | Pointer to a location in a destination buffer. | |
| pKernel | Pointer to the kernel array. | |
| pSrc | Pointer to a location in a source buffer. | |
| srcStep | Source buffer step size (width of the buffer in bytes). | |
| xAnchor | Anchor cell that specifies the horizontal alignment of the kernel with respect to the input pixel. |
These functions step through an ROI in a source buffer, calculate the sum of products of the kernel values and the corresponding pixel values in an area defined by the kernel size and anchor coordinate, then divide by the divisor.
The filtered data is written to a destination buffer.
The horizontal row kernel is an array of signed 32-bit integer values; the anchor coordinate location is relative to the right side of the kernel.
Functions that operate on 8-bit unsigned data assume that the kernel values are small.
If the results of intermediate calculations exceed 24 bits, calculation errors may occur.
For very small kernel values, the functions use very fast code, at the expense of accuracy (+/- 1.5).
