In this article, it is proposed that fourth-order statistics are used for radar imaging rather than second-order statistics. The ad¨antages gained using higher order statistics are demonstrated for both con¨entional Fourier imaging as well as for subspace-based algorithms, e.g., MUSIC. The technique

Abstract
The aim of this work is to present a method for the segmentation of images based on local higher order statistics. The algorithm can be applied for the separation of objects from a texture background and the segmentation of textures. The proposed technique makes no use of a data bank and its complexity is O(𝒩) where 𝒩 is the number of pixels. © 2003 Wiley Periodicals, Inc.
