mlib_ImageSConv7x7 - separable 7x7 convolution SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_ImageSConv7x7(mlib_image *dst, const mlib_image *src, const mlib_s32 *hkernel, const mlib_s32 *vkernel, mlib_s32 scale, mlib_s32 cmask, mlib_edge edge); DESCRIPTION
The mlib_ImageSConv7x7() function performs a separable 7x7 convolution 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]*2**(-2*scale) p=-dm q=-dn where m = 7, n = 7, dm = (m - 1)/2 = 3, dn = (n - 1)/2 = 3. 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. scale Scaling factor. cmask Channel mask to indicate the channels to be convolved, each bit of which represents a channel in the image. The channels corresponding to 1 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. ATTRIBUTES
