#include <mlib.h>

mlib_status mlib_ImageCopyMask_Fp(mlib_image *dst, const mlib_image *src,
    const mlib_image *mask, const mlib_d64 *thresh);

 

DESCRIPTION

The mlib_ImageCopyMask_Fp() function copies one image to another image via a mask image by using it as a yes/no indicator. The data type of the images can be MLIB_FLOAT or MLIB_DOUBLE.

It uses the following equation:

dst[x][y][i] = src[x][y][i]  if mask[x][y][i] ≤ thresh[i]
dst[x][y][i] = dst[x][y][i]  if mask[x][y][i] > thresh[i]

 

PARAMETERS

The function takes the following arguments:

dst

Pointer to destination image.

src

Pointer to source image.

mask

Pointer to mask image.

thresh

Threshold for the mask image. thresh[i] contains the threshold for channel i.

 

RETURN VALUES

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