Aperture Problem

The "Aperture Problem" is a fundamental ambiguity in motion perception, within the broader class of visual motion estimation problems, whereby the observed motion of a spatially limited stimulus through an aperture permits only the detection of motion perpendicular to the local orientation of a contour, leaving the true direction and speed of motion indeterminate.
