Principal purpose of this paper is to extract a facial change among the faces at the different situations for the psychological applications. Because of the difficulties fixing the face location at a particular coordinate, an extraction of the facial change from the comfortable to uncomfortable is relatively difficult task for a computerized approach. To overcome this difficulty, we propose a method, which combines the Fourier with wavelets approaches. After, a global facial change is extracted by the Fourier transform; application of the multi-resolution analysis of wavelets makes it possible to extract the local facial changes.
