NAME
mlib_ImageConv5x5_Fp - 5x5 convolution
SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include <mlib.h>
mlib_status mlib_ImageConv5x5_Fp(mlib_image *dst, const mlib_image *src,
const mlib_d64 *kernel, mlib_s32 cmask, mlib_edge edge);
DESCRIPTION
The mlib_ImageConv5x5_Fp() function performs a floating-point 5x5 con‐
volution on the source image by using the user-supplied kernel.
The input image and the output image must have the same image type and
have the same number of channels. The unselected channels in the output
image are not overwritten. For single-channel images, the channel mask
is ignored.
For this convolution, the key element of the convolution kernel is
located at the center of the kernel matrix.
It uses the following equation:
m-1-dm n-1-dn
dst[x][y][i] = SUM SUM src[x+p][y+q][i]*k[p][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.
kernel Pointer to the convolution kernel, in row major order.
cmask Channel mask to indicate the channels to be convolved, each
bit of which represents a channel in the image. The channels
corresponding to bits with a value of 1 are those to be pro‐
cessed. 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.
