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.
