%X The Binary Phase-Only Filter (BPOF) digital image watermarking embeds the BPOF of the Discrete Fourier Transform (DFT) of an image into one of the bit planes of the corresponding magnitude for image authentication. In this paper, BPOF watermarking based image tampering localization was studied. To detect and localize the tampered regions in an image, the image was divided into non-overlapping blocks, while the watermarks were embedded and detected within the blocks individually. The discussion focused on th...
