Towards change detection in bi-temporal images using evidential conflict

This paper exposes new method of remote sensed imagery change detection based on the framework of Dempster-Shafer. The method is established on multi-temporal conflict analysis and interpretation, where it was used as a new index of change. In consequence, a pre-change card was produced from the multi-temporal conflict card between the two bi-temporal images and which was deduced from the empty-set mass. It is the proof that the Dempster-Shafer Theory can be applied in a new way for change detection where the conflict imperfection allows mining reliable and not trivial information about change. The effectiveness of the conflict for multi-temporal change mapping was demonstrated using bi-temporal Landsat imagery.
