AM-FM demodulation is used for expanding a digital image/video in terms of an AM-FM series expansion. The fundamental AM-FM harmonic is estimated using a collection of bandpass filters which operate over the analytic version of the input image/video. The SIMD architecture was used to develop a fast implementation of the AM-FM decomposition. Preliminary results are shown for a novel fast segmentation of M-mode ultrasound videos, based only on the harmonic estimation.
