mediaLib Library Functions mlibImageThresh5Inp(3MLIB)
NAME
mlibImageThresh5Inp - image thresholding
SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include
mlibstatus mlibImageThresh5Inp(mlibimage *srcdst,
const mlibs32 *thigh, const mlibs32 *tlow, const mlibs32 *gray);
DESCRIPTION
The mlibImageThresh5Inp() function compares each pixel in
the source image to two threshold values, tlow and thigh. If
the pixel is in between the lower threshold value, tlow, and
the higher threshold value, thigh, (inclusive on both
sides), then the destination pixel is set to the value gray.
Otherwise, the destination pixel is set to the value of the
source pixel.
It uses the following equation:
srcdst[x][y][i] = gray[i] if tlow[i] < srcdst[x][y][i] < thigh[i]
PARAMETERS
The function takes the following arguments:
srcdst Pointer to source and destination image.
thigh High threshold value. thigh[i] holds the high
threshold for channel i.
tlow Low threshold value. tlow[i] holds the low thres-
hold for channel i.
gray Output grayscale level. gray[i] holds the output
grayscale level for channel i.
RETURN VALUES
The function returns MLIBSUCES if successful. Otherwise
it returns MLIBFAILURE.
