If LSB technique is combined with any frequency domain (DCT, DWT,SVD etc.) watermarking scheme. Is this technique (DWT-LSB) or(DCT-LSB) etc. can be considered as hybrid domain watermarking?
OR only two frequency domain techniques are combined than it is termed as Hybrid domain?
Dear Sanjay Kumar
Basically, This work proposes a hybrid watermarking approach for multimedia data such as digital images and digital videos. To accomplish fragility and security for multimedia data, the approach employs multiple image processing transformations including Compressive Sensing (CS).
However, A way for digital watermarking is to layer a visible sign on top of a picture. At the top, a symbol symbolizes the copyright for that image, and it can be differentiated from the others.
