Witryna1 sie 2024 · Abstract. This paper suggests a sparse watermark image embedding scheme on the singular values of the pre-selected wavelet sub-band coefficients of the digital images. Dictionary learning (DL) method is used to make the watermark image sparse. Then a watermark decoder is designed based on the theory of compressed … WitrynaThis paper discusses a new video watermarking scheme which is non-blind hybrid technique based on singular value decomposition (SVD) and discrete wavelet transform (DWT). The proposed hybrid algorithm partitions the host image into blocks and each of them is transformed into U, S and V components by SVD. And then, a set of blocks …
