This paper presents an image improvement algorithm using phase congruency map and multi-resolution transforms. The main idea relies on the fact that we want to increase the informational content (to make some features "more visible") from a damaged image by using phase information. The feature map result is combined with the original image using multi-resolution through a fusion process. This algorithm has been created to be used on satellite images, because the informational content of such images can be easily damaged as a result of the acquisition process or as a result of the weather conditions. This is the reason why we want to enhance them by using phase congruency which is a robust detector for illumination variation and scale.
