It makes it compatible with the desired industrial constraints, i.e. The whole scheme has a high efficiency and a low computational cost. Color corrections also enhance the watermarking score. Experiments on 400 ID images show that the Wiener filter strongly improves the detection rate and outperforms competitive algorithms (blind deconvolution and unsharp filter. ![]() The second comprises a filter that reduces image blurring. The first is a watermarking algorithm based on the Fourier transform to cope with global geometric distortions. ![]() In this work, a robust watermarking technique is presented in this context. The major challenge is resistance to attacks: printing the images on the plastic cards, durability and other attacks then scanning the image from the plastic card. Robust Fourier Watermarking for ID Images on Smart Card Plastic Supportsĭirectory of Open Access Journals (Sweden)įull Text Available Security checking can be improved by watermarking identity ( ID images printed on smart cards plastic supports.
