Summary
Recent research has witnessed an explosive increase in
models that treat percepts as optimal probabilistic inference
[1­13]. The ubiquity of partial camouflage and occlusion in
natural scenes, and the demonstrated capacity of the visual
system to synthesize coherent contours and surfaces from
fragmented image data, has inspired numerous attempts to
model visual interpolation processes as rational inference
[9­13]. Here, we report striking new forms of visual interpo-
lation that generate highly improbable percepts. We present
motion displays depicting simple occlusion sequences that
elicit vivid percepts of illusory contours (ICs) in displays for
