Nested random phase sequence sets: a link between AM-FM demodulation and increasing operators with application to cardiac image analysis


AM-FM models images as a linear combination of positive amplitude modulated (AM) sinusoids with non-linear phase functions. We develop a novel FM harmonics operator for revealing different levels of image structure detail. The new operator is defined in terms of known AM-FM demodulation techniques: dominant component analysis and channelized component… (More)
