mlib_ImageSConvKernelConvert - kernel conversion for separable convolution
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);
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.
The function takes the following arguments:
Pointer to integer horizontal kernel.
Pointer to integer vertical kernel.
Scaling factor of the integer convolution kernel.
Pointer to floating-point horizontal kernel.
Pointer to floating-point vertical kernel.
Width of the convolution kernel. m must be an odd number larger than 1.
Height of the convolution kernel. n must be an odd number larger than 1.
The image type.
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
