An efficient method for satellite image matching and management

A method for matching two different images is discussed in this paper. Image matching is to match an image with other image that may has different properties. In the matching, generally the images are the same in appearance, may contain quite different contents. If there is no noise, identical pixel value and unchanged edges in those, image matching process can be operated by very simple model. However, natural images to be matched in the most application do not have such an ideal circumstance. This paper proposes a compression method for archiving satellite images and matching scheme which is to match GCP images with a raw satellite image. The proposed method is based on wavelet transform, not required any pre-processing such as histogram equalization, noise reduction.
