NAME

       mlib_ImageSConvKernelConvert - kernel conversion for separable convolution

SYNOPSIS

       cc [ flag... ] file... -lmlib [ library... ]
       #include <mlib.h>

       mlib_status mlib_ImageSConvKernelConvert(mlib_s32 *ihkernel, mlib_s32 *ivkernel, mlib_s32 *iscale, const mlib_d64 *fhkernel, const mlib_d64
       *fvkernel, mlib_s32 m, mlib_s32 n, mlib_type type);

DESCRIPTION

       The mlib_ImageSConvKernelConvert() function converts a floating-point separable convolution kernel to an integer kernel	with  its  scaling
       factor, which is suitable to be used in separable convolution functions.

PARAMETERS

       The function takes the following arguments:

       ihkernel        Pointer to integer horizontal kernel.

       ivkernel        Pointer to integer vertical kernel.

       iscale	       Scaling factor of the integer convolution kernel.

       fhkernel        Pointer to floating-point horizontal kernel.

       fvkernel        Pointer to floating-point vertical kernel.

       m	       Width of the convolution kernel. m must be an odd number larger than 1.

       n	       Height of the convolution kernel. n must be an odd number larger than 1.

       type	       The image type.

RETURN VALUES

       The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.

NAME

       mlib_ImageSConv3x3 - separable 3x3 convolution

SYNOPSIS

       cc [ flag... ] file... -lmlib [ library... ]
       #include <mlib.h>

       mlib_status  mlib_ImageSConv3x3(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_ImageSConv3x3() function performs a separable 3x3 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 = 3, n = 3, dm = (m - 1)/2 = 1, dn = (n - 1)/2 = 1.

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 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.
