heal.abstract	Locally narrow-band images can be modeled as two-dimensional (2D) spatial AM - FM signals with several ap- plications in image texture analysis and computer vision. We formulate an image-demodulation problem and present a solution based on the multidimensional energy operator Fs f d › k=fk 2 2 f = 2 f . This nonlinear op- erator is a multidimensional extension	en
