NAME

mlib_ImageThresh3 - image thresholding  

SYNOPSIS

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

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 output level for channel i.

 

RETURN VALUES

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