Do I need a header to define the threshold function?

RE :Threshold function

Code:

void Threshold (int **in_image, int x_max, int y_max, int threshold)
{
for(int x=0; x<x_max; x++)
{
for(int y=0; y<y_max; y++)
{
if (in_image[x][y] >= threshold)
in_image[x][y] = 255;
else
in_image[x][y] = 0;
}
}
}

I need a header or something to define the threshold function right?coz C++ itself doesnt understand wat's a threshold i suppose.. :roll:

Do i need pointers to do the static 2D-arrays(**in_image) instead?
Thanks!!

Re: RE :Threshold function

Hi,
You may define the image array to be one dimensional and then access using offset. All arrays are one dimensional. The interpretation just changes for 2D arrays.
I hope this helps.
