Multi-scale low rank versus low rank + sparse decomposition on a surveillance video. For the multi-scale low rank, body motion is mostly captured in the 16 × 16 × 16 scale while fine-scale motion is captured in 4 × 4 × 4 scale. Background video component is captured in the globally low rank component and is almost artifact-free. Low rank + sparse decomposition exhibits ghosting artifacts as pointed by the red arrow because they are neither globally low rank or sparse.
