The relation between the subjective evaluation of "iyashi" and the characteristic parameters of the stimulus portraits is analyzed using the approach of quality engineering.20 portraits taken from classical paintings are presented to 113 subjects,and each subject is requested to answer the degree of "iyashi" felt from each portrait by three-grade evaluation.17 facial expression parameters are extracted from each portrait.The model to estimate "iyashi" degree from the expression parameters is created for each subject using the two-sided Taguchi method of quality engineering.The unit space is considered as the weighted average of the 20 portraits,and the weight vector which maximizes the SN ratio of the comprehensive estimation is obtained for each subject.As a result,it is found that among the portraits which have the maximum unit space weight(basis portrait),there exist the pictures on which many subjects concentrate.Similarly,it is found that among the expression parameters which have large SN ratio in the model equation(major expression parameter),there exist the parameters on which many subjects concentrate.As the result of applying the quantification method I to estimate the basis portrait number from the 3 major expression parameters,the multiplecorrelation coefficient is 0.83 and it is shown that a certain relation exists between the basis portrait and the major expression parameters.
