mediaLib Library Functions mlibImageThresh1Inp(3MLIB)
NAME
mlibImageThresh1Inp - image thresholding
SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include
mlibstatus mlibImageThresh1Inp(mlibimage *srcdst,
const mlibs32 *thresh, const mlibs32 *ghigh, const mlibs32 *glow);
DESCRIPTION
The mlibImageThresh1Inp() function compares each pixel in
the image to a threshold value on a per-channel basis. If
the pixel is less than or equal to the threshold value, then
it is reset to the low output level. If the pixel is greater
than the threshold value, then it is reset to the high out-
put level.
It uses the following equation:
srcdst[x][y][i] = glow[i] if srcdst[x][y][i] < thresh[i]
srcdst[x][y][i] = ghigh[i] if srcdst[x][y][i] > thresh[i]
PARAMETERS
The function takes the following arguments:
srcdst Pointer to source and destination 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.
glow Low output level. glow[i] contains the low output
level for channel i.
RETURN VALUES
The function returns MLIBSUCES if successful. Otherwise
it returns MLIBFAILURE.
