Remove watermark from video Is there a process to remove a watermark ever present across all frames of a video?
I was thinking that comparing frames and taking pairs poorly correlated, could give a clue about the watermark both share. Or perhaps merging or adding all the frames could reveal the strong watermark pattern. O maybe is a work for a neural network.
The presence of this fixed pattern between other variable information make me think is feasible. I will be glad to read your insights about this problem.
If the watermark is additive and static and, the content is smooth, and the vide long enough you could compute the watermark that minimizes $\sum ||S(F_i - W)||^2$, for the frames $F_i$ and a fixed watermark $W$. The solution $W$ is expected to converge to the watermark.
But it is always better to use the original video.
