Fast logo insertion method based on DCT domain
A novel method of logo insertion in MPEG-2 video is proposed. Compared to the method of Decompression-Addition-Recompression, it needs neither DCT and inverse DCT transformation nor motion estimation. Therefore, computational complexity is reduced and it is quite suitable for real-time procession. The experimental result shows that the proposed method has almost the same effect as pixel domain processing method.
