Title: METHOD AND APPARATUS FOR GENERATING AN ENHANCED DIGITAL IMAGE OF A PHYSICAL OBJECT OR ENVIRONMENT
Abstract:
A method and apparatus are provided for generating enhanced digital imagery from digital input images (7) exhibiting differences other than or in excess of differences in projection. By applying a plurality of image transformations (10) to frequency normalised (8) versions of the input images, and generating measures of image similarity (11) therefrom, an optimum image transformation (12) can be determined that can be applied to the digital input images such that they are substantially matched. Digital input images of physical objects or environments to which the method is applied can then be used in image fusion, ortho-rectification or change detection applications, in order to monitor the physical object or environment.
