mediaLib Library Functions mlib_ImageThresh3(3MLIB)
NAME
mlib_ImageThresh3 - image thresholding
SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include
mlib_status mlib_ImageThresh3(mlib_image *dst, const mlib_image *src,
const mlib_s32 *thresh, const mlib_s32 *ghigh);
DESCRIPTION
The mlib_ImageThresh3() function compares each pixel in the
source image to a threshold value. If the pixel is less than or equal to the threshold value, then the destination pixel is set to the value of the source pixel. If the pixel is greater than the threshold value, then the destination pixel is set to the high output level. It uses the following equation: dst[x][y][i] = src[x][y][i] if src[x][y][i] < thresh[i] dst[x][y][i] = ghigh[i] if src[x][y][i] > thresh[i]PARAMETERS
The function takes the following arguments: dst Pointer to destination image. src Pointer to source image. thresh Threshold value. thresh[i] contains the threshold for channel i.ghigh High output level. ghigh[i] contains the high out-
put level for channel i.RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise
it returns MLIB_FAILURE.
