Abstract
A technique is presented for extracting phase information from a pair of sinusoidal signals, with equal frequency, but different phase angle, by convolving each signal with a pair of quadrature Gabor filters.
It is shown that, under certain conditions, Gabor filters can be treated as linear functions. The applications of the Gabor filter are discussed with respect to both image processing, and extracting phase information from sinusoidal signals in minimum time.
