| summary |
One approach to understanding human texture discrimination is to consider what image properties should be examined by a system which computes it. This is investigated in a domain of line drawings. It appears that the orientation and length of lines should be examined. However, there exist textures in which these properties are identical yet discrimination occurs. Consideration of virtual lines (imaginary lines between special points) is introduced to explain such textures. The relation of this method to that of Julesz is discussed with the conclusion that it is strictly less powerful. This lack of sensitivity appears to be psychologically correct; instances are given of indiscriminable textures with different second-order statistics but identical (equivalent) actual and virtual lines. An implementation of the computation is sketched |
