Text-image watermarking based on integer wavelet transform (IWT) and discrete cosine transform (DCT)
Text-images still have a great importance, despite the spread of electronic texts. Text-images are protected using digital watermarking. This paper proposes a watermarking method applied to text-images. This method integrates two transforms: integer wavelet transform (IWT) and discrete cosine transf...
