heal.abstract	Locally narrowband images can be modeled as 2D spatial AM-FM signals with several applications in image texture analysis and computer vision. In this paper we formulate such an image demodulation problem, and present a solution based on the multidimensional energy operator Φ(f)=\|\|∇f\|\|2-f∇2f. We discuss some interesting properties of this multidimensional operator and develop multidimensional energy separation algorithms to estimate the	en
