Abstract

Analyzing functions with small values of the product of position and frequency uncertainties have many advantages in image processing and data compression. Until now, this value has been computed based on the uncertainty principle, but the computed frequency uncertainty is not practical for the human visual filters which have non-zero peak response frequencies. A new metric for the frequency uncertainty is used to calculate a deviation about the frequency which has the maximum response. The joint effective widths for various functions are derived. As the result of analysis, the joint uncertainty for many functions converges to 0.5 as the joint parameter increases. Furthermore, Gabor cosine function shows an excellent performance among the mentioned functions.
