The invention comprises a procedure for conditioning and perfuming textiles and a product suitable for carrying out this procedure, with a long-lasting persistence of the perfuming effect in the garments. The present invention is characterized in that eigenvectors and weights are extracted from the input facial image using principal component analysis and the extracted eigenvectors and weights of the user image are substituted into a occluding-decision algorithm, whereby it can be determined whether the facial image is occluded. The CT image processor calculates the displacement in the positions of the liver determined by the CT and PET images.
