Abstract : The issue of co-registration distortions between images is one of major problems involved in data fusion processes. This conclusion can be extended to change detection generally also performing on a pixel basis. Accurate methods are therefore required for co-registration of images in these particular cases. It is the reason why we present a co-registration method using multi-resolution analysis and local deformation models. This work includes a validation protocol that enables the assessment of the accuracy, the robustness and the quality provided by any co-registration method. This validation protocol has been then applied to the presented method and the results have been compared to those provided by a standard one. According to this validation, this method provides a very fine correction of the geometric distortions that is better than those generally provided by standard co-registration methods. As a conclusion, this method seems to constitute an answer to the need of high quality co-registration as a pre-processing of fusion and change detection processes. Moreover, it is a fully automatic method that potentially enables an operational utilisation of high quality.
