Removes fixed point camera noise from the image using a more robust method than Function:fpn. In addition to black image, the function also takes a white image and gain value to remove noise from the input image using the internal formula: dst[i] = Saturate(gain * (src[i]- black[i])/(white[i] - black[i]),0,maxValue);
