Abstract

Due to the use of the digital video, video block error including watermarking error in the digital video may cause serious error propagation and quality degradation. A deblocking technique is applied for digital watermarking by graphics process. In the study the processes of constructing and reconstructing a digital video frame are described on the basis of the theory of video coding. The conditions for deblocking the digital video frames are investigated in detail. The validity of the present method is verified by experimental data and the simulation result shows with GPU deblocking support us to improve the video quality effectively. In this paper we will introduce a new deblocking filter which based on hardware GPU which applied in our watermarking system.
