MOTION CAPTURE ANISOTROPY

摘要: Abstract Two uncorrelated random dot patterns were superimposed and alternated to produce dynamic incoherent noise. When a low spatial frequency sine wave grating was optically on this noise moved in step with the alternation of two frames, motion masked all dots seen adhere move it as single rigid sheet (“Motion Capture”). Over wide range displacements subjects could not discriminate which “captured” from correlated physically same direction grating. In fact signal even strong enough overcome signals twocorrelated opposite direction. Capture if orthogonal motion. We conclude that any visual scene certain salient features image tends dominate our perceptual experience. The frequencies masks or inhibits high frequencies. Since latter now have no their own they are assumed Thus, capture suggests an important biological role for long-range apparent motion: process serves preserve continuity object identity while at time eliminating spurious arise finer features. manner system solves “correspondence problem” without benefit either computation cognition.
