This paper extends earlier work by Morrone and Owens (1987) on the local energy feature detection scheme by explicitly identifying the class of images that are feature-free, that is, for which the local energy function has no local maxima. It is shown that the phase congruency function, which measures the degree of order in the phase spectrum of the image, uniquely represents that image apart from a feature-free image. This results in a demonstration that the features in an image, that is, those points at which the local energy function has a local maximum, are stable with respect to a large class of image variations.
