An enhanced approach in video watermarking with multiple watermarks using wavelet

Аннотация

Watermarking technology is an effective method to clarify the problem of protecting multimedia information. It is the expertise of concealing the information into a host such that the embedded data is invisible. In our strategy luminance band of the selected frames is taken further, it is grouped to alternative pixel shares and flip those images. Two color watermark images are split into distinctive pieces and concatenate its layers, further it is embedded into respective flipped shares under wavelet. Unfold the shares into normal image and stack the designations into single luminance layers. Results achieved the quality of the watermarked frame is high and also the concealed data is requested with acceptably by the human visual system which makes them undetectable. Extraction guarantees that the watermark could be effectively recaptured from a quite short portion of the video. Disguised data are less discernible as well as strong against regular video processing attacks.
