NAME
mlib_ImageThresh1_Inp - image thresholding
SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include <mlib.h>
mlib_status mlib_ImageThresh1_Inp(mlib_image *srcdst, const mlib_s32 *thresh, const mlib_s32 *ghigh, const mlib_s32 *glow);
DESCRIPTION
The mlib_ImageThresh1_Inp() 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 output 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 output level for channel i.
glow Low output level. glow[i] contains the low output level for channel i.
RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
