Computational Modeling Of Depth-Ordering In Occlusion 
Through Accretion Or Deletion Of Texture, Harald Ruda, Gennady Livitz, Guillaume Riesen, Ennio Mingolla

MODVIS Workshop

Understanding the depth-ordering of surfaces in the natural world is one of the most fundamental operations of the primate visual system. Surfaces that undergo accretion or deletion (AD) of texture are always perceived to behind an adjacent surface.

An updated ForMotionOcclusion (FMO) model (Barnes & Mingolla, 2013) includes two streams for computing motion signals and boundary signals. The two streams generate depth percepts such that AD signals together with boundary signals generate a farther depth on the occluded side of the boundary. The model fits the classical data (Kaplan, 1969) as well as the observation that moving surfaces tend to …
