NAME

mlib_ImageThresh5_Fp_Inp - image thresholding  

SYNOPSIS

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

mlib_status mlib_ImageThresh5_Fp_Inp(mlib_image *srcdst,
    const mlib_d64 *thigh, const mlib_d64 *tlow, const mlib_d64 *gray);

 

DESCRIPTION

The mlib_ImageThresh5_Fp_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.
