I’ll focus on the following paper, which won an Outstanding Student Paper Award at the most recent NIPS conference:
Analysis of Contour Motions,
Ce Liu, William T. Freeman, and Edward H. Adelson
In addition, I will likely draw on the following papers, which are also related to motion of boundaries and occlusion events:
Disambiguating Visual Motion by Form-Motion Interaction — a Computational Model,
by Bayerl, P. & Neumann, H., in IJCV, April 2007.
Beyond junctions: nonlocal form constraints on motion interpretation,
by Josh McDermott, Yair Weiss, and Edward H. Adelson, in Perception 2001.
