WebApr 12, 2024 · While jiggling that embedding would produce non-coherent movements in the resulting video, this work proposes two novel post-hoc techniques to enforce temporally consistent generation by encoding motion dynamics in latent codes and reprogramming each frame’s self-attention using cross-frame attention (see the figure below for more … WebMay 1, 2010 · Existing video matting approaches determine the alpha matte sequence frame-by-frame, which lead to flickering near the boundary of the foreground region. We reduce this effect by considering video data as a spatio-temporal cube, and extending a robust matting algorithm to a 3D solver.

Weblarization step in order to produce coherent video mattes. This paper contributes to video matting by incorporat-ing motion information in the so-called KNN Laplacian to make it motion-aware. This is the ﬁrst attempt to empir-ically show this simple strategy is effective in producing spatio-temporally coherent pixel clusters of moving pixels.
