do you mean specifically preserving continuity from one frame to the next?
No, I don't see any reason that this would avoid flickering. The method is chaotic and processes a 2D image, not a 3D image-time volume.
With GPU, I think it is possible
I don't see how GPUs are relevant. The question wasn't about real time video, but video without flickering. I don't have the domain knowledge to answer confidently, but the algorithm was designed to be noise-tolerant. From my own amateur-level reading of the paper I see no reason why it shouldn't work well with video.
