```mlib_ImageThresh5_Fp(3MLIB)				    mediaLib Library Functions				       mlib_ImageThresh5_Fp(3MLIB)

NAME
mlib_ImageThresh5_Fp - image thresholding

SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include <mlib.h>

mlib_status  mlib_ImageThresh5_Fp(mlib_image  *dst,  const  mlib_image  *src,  const  mlib_d64 *thigh, const mlib_d64 *tlow, const mlib_d64
*gray);

DESCRIPTION
The mlib_ImageThresh5_Fp() 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:

dst[x][y][i] = src[x][y][i]  if src[x][y][i] < tlow[i]
dst[x][y][i] = gray[i]	    if tlow[i] <= src[x][y][i] <= thigh[i]
dst[x][y][i] = src[x][y][i]  if src[x][y][i] > thigh[i]

PARAMETERS
The function takes the following arguments:

dst	       Pointer to destination image.

src	       Pointer to source image.

thigh	       High threshold value.  thigh[i] holds the high threshold for channel i.

tlow	       Low threshold value.  tlow[i] holds the low threshold for channel i.

gray	       Output grayscale level.	gray[i] holds the output grayscale level for channel i.

RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.

NAME
mlib_ImageThresh5_Inp - image thresholding

SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include <mlib.h>

mlib_status mlib_ImageThresh5_Inp(mlib_image *srcdst, const mlib_s32 *thigh, const mlib_s32 *tlow, const mlib_s32 *gray);

DESCRIPTION
The  mlib_ImageThresh5_Inp()  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 threshold for channel i.

gray	       Output grayscale level.	gray[i] holds the output grayscale level for channel i.

RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
