| Abstract(in English) | We examined the effects of spatial frequency of the square wave part on appearance of the cafe wall illusion. At moderately high frequencies, an intriguing phenomenon was found. Each tile appeared an independent trapezoid instead of connected elongated trapezoid seen with regular illusion, thus the top and bottom edges of each row appeared in a saw-tooth shape. This is the result that it is impossible to integrate the local and global orientation of the twisted cords that appear in the mortar as a result of hand-pass filtering within the visual system, so that the local one is excessively slanted. |
