An imroved image demodulation algorithm based on Teager-Kaiser operator (original) (raw)

2008 3rd International Symposium on Communications, Control and Signal Processing, 2008

Abstract

In this paper a new wideband image demodulation algorithm based on the Teager-Kaiser operator is proposed. A Gabor filter bank is first used to decompose the wideband image into multiple narrow band components. Directly applied on these components, the demodulation yields many artifacts on both the amplitude and the frequency modulation counterparts. To reduce these artifacts, a low-pass filter in
