NAME
mlib_ImageSobel, mlib_ImageSobel_Fp - Sobel filter
SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_ImageSobel(mlib_image *dst, const mlib_image *src, mlib_s32 cmask, mlib_edge edge); mlib_status mlib_ImageSobel_Fp(mlib_image *dst, const mlib_image *src, mlib_s32 cmask, mlib_edge edge);
DESCRIPTION
Each function is a special case of the gradient filter, which is an edge detector which computes the magnitude of the image gradient vector in two orthogonal directions. In this case, the gradient filter uses specific horizontal and vertical masks. The Sobel filter is one of the special cases of gradient filter using the following horizontal and vertical masks: hmask = { -1.0, 0.0, 1.0, -2.0, 0.0, 2.0, -1.0, 0.0, 1.0 } vmask = { -1.0, -2.0, -1.0, 0.0, 0.0, 0.0, 1.0, 2.0, 1.0 }
PARAMETERS
Each function takes the following arguments: dst Pointer to destination image. src Pointer to source image. cmask Channel mask to indicate the channels to be processed, 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_DS_FILL_ZERO MLIB_EDGE_DST_COPY_SRC MLIB_EDGE_SR_EXTEND
RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
