WitrynaDigital images can be easily copied or manipulated by irresponsible persons. The right property needs to be secured and protected from illegal copies and piracy. Digital … Witryna17 sie 2024 · The DWT approach is an effective process and is probably superior when watermarking is applied to the entire image [29,30]. Determining a favorable watermarking zone for bit embedding is a complex process, and it must proceed through various calculative operations for setting up.

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 …

WitrynaTo show the effectiveness of LTP watermarking, certain attacks like cropping, noise, and compression are applied. As a result, the extracted watermark is tempered. DCT ensures robustness by compressing the image while LTP allows watermark embedding and extraction.

A bit of binary watermark is embedded into one point of a center line in an embedding primitive. Thus, a n th watermark bit w n is embedded into the length ln of center line as follows; if 1w n, then ln t ln. Otherwise, ln ln. ln is an average length of the connected Lines.
