Abstract
Requirement of long-term use of existing buildings has been increasing in aspect of environmental and economical issues, and the visual impression of building materials from the view point of aesthetics is considered as an important factor for long-term use of buildings. In this research, the new methodology by using 2dimensional Fourier Transformation has been developed for evaluation of stains on exposed concrete surfaces. As a result, various shapes of stains on the constant distance have been explained by the slope of power spectra by frequencies which make up a digital image including stains.
