NAME
mlib_ImageSConv5x5_Fp - separable 5x5 convolution
SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include <mlib.h>
mlib_status mlib_ImageSConv5x5_Fp(mlib_image *dst, const mlib_image *src,
const mlib_d64 *hkernel, const mlib_d64 *vkernel, mlib_s32 cmask,
mlib_edge edge);
DESCRIPTION
The mlib_ImageSConv5x5_Fp() function performs a separable 5x5 convolu‐
tion on the source image by using the user-supplied kernel.
It uses the following equation:
m-1-dm n-1-dn
dst[x][y][i] = SUM SUM src[x+p][y+q][i]*h[p]*v[q]
p=-dm q=-dn
where m = 5, n = 5, dm = (m - 1)/2 = 2, dn = (n - 1)/2 = 2.
PARAMETERS
The function takes the following arguments:
dst Pointer to destination image.
src Pointer to source image.
hkernel Pointer to the horizontal kernel.
vkernel Pointer to the vertical kernel.
cmask Channel mask to indicate the channels to be convolved, each
bit of which represents a channel in the image. The channels
corresponding to one bits are those to be processed. For a
single-channel image, the channel mask is ignored.
edge Type of edge condition. It can be one of the following:
MLIB_EDGE_DST_NO_WRITE
MLIB_EDGE_DST_FILL_ZERO
MLIB_EDGE_DST_COPY_SRC
MLIB_EDGE_SRC_EXTEND
RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns
MLIB_FAILURE.
