Abstract EN
Invoice printing just has two-color printing, so invoice font image can be seen as binary image.
To embed watermarks into invoice image, the pixels need to be flipped.
The more huge the watermark is, the more the pixels need to be flipped.
We proposed a new pixels flipping method in invoice image for huge watermarking capacity.
The pixels flipping method includes one novel interpolation method for binary image, one flippable pixels evaluation mechanism, and one denoising method based on gravity center and chaos degree.
The proposed interpolation method ensures that the invoice image keeps features well after scaling.
The flippable pixels evaluation mechanism ensures that the pixels keep better connectivity and smoothness and the pattern has highest structural similarity after flipping.
The proposed denoising method makes invoice font image smoother and fiter for human vision.
Experiments show that the proposed flipping method not only keeps the invoice font structure well but also improves watermarking capacity.
