Figure 14

(a) Different configurations of the Café Wall pattern tested (Figure 13) from Café Wall of 3 × 11 tiles on the top to Café Wall of 11 × 11 tiles at the bottom. (b) Mean tilts and the standard errors of tilt angles for each variation are summarized in the mean tilt tables for the four reference orientations of horizontal (H), vertical (V), and diagonals (, ) orientations at seven scales of the edge maps ( = 4, 8, 12, 16, 20, 24, and 28).
