The image processing system to predict three-dimensional drape image from the two-dimensional drape photo image was constructed on a basis of the three-dimensional drape images seen from different angles by using this experimental system and these predicted drape images were compared with the drape images observed at different angles. The results obtained are as follows ; Using the revised height coefficient (k=5), three-dimensional drape image seen from different angles were computed by the

... oth-shading method. The predicted drape images were different from the measured drape images at the salient feature and the re-entrant feature of the drape images. So the revised height coefficient (kb =kr=km=1) of the suspected colored parts (blue, red and madder red) was
