WebA graph wavelet transform-based steganography using graph signal processing (GSP) is presented, which results in better visual quality stego image as well as extracted secret image. In the proposed scheme, graph wavelet transforms of both the cover image and transformed secret image (using Arnold cat map) are taken followed by alpha blending ... WebFeb 10, 2024 · The feature of the ECG signal is removed by the changeable parameter with time by applying some signal processing approach because the graph obtained from analysis is not clear in the case of graphical ECG signal. For analysis purpose a type of WT that is Daubechies wavelet transform is a robust device.
