Structure from motion (psychophysics)

Structure from motion (SFM) refers to how humans recover depth structure from rotating objects.

  1. SFM from 1st order velocities.[1]
  2. SFM from 2nd order optic flow and perspective effects.[2]
  3. Surface slant from def.[3]
  4. Some authors report that for non-forntoparallel axes of rotation the perceived shape is distorted beyond a depth scaling factor.[4]
