The term ‘deteriorated texture’ gives all experts as well as ordinary people almost the sameimpression. Despite common points in images, the differences put Iran cities in different categories based on deteriorated textures. This classification not only has negative effect on the audience from mental point of view but causes various problems for the experts in determining interference method. For example, the textures having different deterioration causes yet from body point of view have led to the same deterioration placed under the same category. This itself leads to new problems and results in the deterioration process. So, this study has based its performance on deterioration indicators through investigating different definitions of deterioration and putting aside formal definitions of deteriorated textures. Then, having reviewed interference perspectives, we put the final frame on deterioration indicators. We have analyzed several interference projects in deteriorated textures in order to come up with a theoretical framework and arrive at basic criteria. Of course, it should be mentioned that we have tried to select projects whichhave common condition with Iran so that the resulted criteria can be applied in deteriorated texture in Iran.
