Visual Processing of Object Velocity and Acceleration.
Abstract
The main objective of this project was the analysis of the detection of trajectory signals in random motion noise. Results from experiments demonstrated that detection was limited by the probability of mismatch, not noise density per se; detection was based on a motion signal, not a form or position signal; detection was limited by higher-order aspects of motion processing, not the ratio of signal to noise in the primary motion detectors. The Yuille-Grzywacz "Motion Coherence" model was modified to provide a computational model for these findings. Computer simulations showed that this model was adequate to reproduce our results. In addition, three other projects were supported by this grant: motion transparency from speed signals alone; speed discrimination for targets moving in depth; trajectory motion detection in three-dimensional noise. Nine papers from this project have been accepted in referred journals; one additional paper has been submitted. Four chapters were also supported by this grant. (AN)
