Figure 1: (a) Motion features. Estimates of feature displacements (lines) and associated error covariances (ellipses). (b) Assignment of motion measurements to two components. Weightings are illustrated using colors (red : background ( 𝑤 𝑖 , 1 large), blue : foreground ( 𝑤 𝑖 , 2 large)). (c) Values of displacement estimates 𝐝 𝑖 = [ 𝑢 𝑖 , 𝑣 𝑖 ] 𝑇 . Ellipses visualize the covariances of the two distributions.
