I want to embed a digital image watermark using Fractional Fourier Transform. FrFT converts an image to complex form. How can I embed this watermark with complex values as zeros and ones?

I have a 64x64 grayscale image. I converted it into Binary. Applied 2D-FrFT. It gives complex values. How can it be embedded in a host image as 0 or 1 now?
