Ideal Observers for Detecting Motion: Correspondence Noise

  title={Ideal Observers for Detecting Motion: Correspondence Noise},
  author={Hongjing Lu and Alan L. Yuille},
We derive a Bayesian Ideal Observer (BIO) for detecting moti on and solving the correspondence problem. We obtain Barlow and Tr ipathy’s classic model as an approximation. Our psychophysical expe riments show that the trends of human performance are similar to the B ayesian Ideal, but overall human performance is far worse. We invest igate ways to degrade the Bayesian Ideal but show that even extreme degr adations do not approach human performance. Instead we propose that h umans perform motion… CONTINUE READING
