N2 - Previous approaches to separating transparently combined moving images have focused on the estimation of multiple velocities in a given image patch. This paper extends the definition of support from an exclusively spatial notion, to include the spatio-temporal energy domain. The key insight is that when processing transparent motion displays, the support of a motion hypotheses should exist over both a region of space and velocity, so that it can be isolated both spatially and in terms of local velocity. With this formulation, two layers can have spatially overlapping support, but not be `conflicting' since they are distinct in the spatio-temporal energy domain.
