Abstract
We examined the validity of perceived blur edge width (PBEW) by analyzing the correlation between observer rating values and physical properties that were extended blur edge width (EBEW) and PBEW. We also examined the correlationwith changing contrast sensitivity function (CSF) models in the calculation of PBEW. In our results, PBEW correlatedmore with the observer’s rating values than EBEW. It was also shown that Spatio-Velocity CSF model is significant forcalculating PBEW.
