Abstract :
This paper deals with the watermarking problem for irregular shaped objects in video. Extracting the meaningful objects from video, we have implemented the watermarking using the SA-DCT (shape adaptive discrete cosine transform) and conventional rectangular based watermarking using various padding methods. The experimental results show that the SA-DCT method is superior to all other padding methods in terms of the robustness against the image deformations such as lossy compression, additive noise, filtering, and clipping.
