“…Previous works on slant perception using textured rectangles also demonstrated the little or modest effect of texture gradients (Saunders & Backus, 2006a; Todd & Norman, 2003; Zimmerman et al, 1995). The regular texture yielded more effect than the irregular texture, which was consistent with the previous findings showing that regular textures contain more depth information and thus contribute to the more salient, veridical perception of slant (Kraft & Winnick, 1967; Newman et al, 1973; Saunders & Backus, 2006b; Velisavljević & Elder, 2006). Grid or checkerboard textures may be more effective than the “regular” texture used in the present study, as they appear to have more information on a slant (see Anderson et al, 1998; Todd et al, 2005).…”

“…Instead of the Mahjong figure and the two-disk figure, regular and irregular textures were adopted (Figures 3B and C). Since regular textures yield more accurate slant perception (i.e., less underestimation of slant) than irregular textures (Kraft & Winnick, 1967; Newman et al, 1973; Velisavljević & Elder, 2006), it was expected that the regular texture would cause a more illusory effect. As in Experiment 1, the original surface images were 400 (W) × 560 (H) pixels in size and were stretched and pasted on the virtual square texture using 3D graphic software.…”

Humans perceive 3D shapes even from 2D images. A slant can be perceived from images of slanted rectangular objects, which include texture gradients and linear perspective contours. How does the visual system integrate and utilize these pictorial depth cues? A new visual illusion that provides some insights into this issue was examined. A box-like object with disk figures drawn on its upper surface was rendered in a linear perspective image. The length of the object's upper surface side line was overestimated, probably due to the foreshortened disks serving as slant cues. This illusory effect occurred even when observers estimated the line length on the image plane, suggesting that the slant perception from the disks was mandatory. Five experiments revealed that multiple depth cues were utilized for the slant perception; the aspect ratio of the disks, texture gradients, trapezium/parallelogram contours, and the side surfaces of the box-like object. However, foreshortened disks outside the object were not utilized as depth cues. These results suggested that various depth cues belonging to the target object are integrated for the slant perception.

“…Past research on the perception of slant, conducted mostly with computer-generated texture patterns, has typically shown underestimation (e.g., Andersen et al, 1998;Gibson, 1950b;Newman et al, 1973;Rosas et al, 2004;Saunders, 2003;Todd et al, 2005). The observers in our Experiment 2 also exhibited underestimation when they judged the surface slants by using magnitude estimation (see Figure 8).…”

Effects of 3-D Complexity on the Perception of 2-D Depictions of Objects

In a recent study, Pelli (1999 Science 285 844-846) performed a set of perceptual experiments using portrait paintings by Chuck Close. Close's work is similar to the 'Lincoln' portraits of Harmon and Julesz (1973 Science 180 1194-1197) in that they are composite images consisting of coarsely sampled, individually painted, mostly homogeneous cells. Pelli showed that perceived shape was dependent on size, refuting findings that perception of this type is scale-invariant. In an attempt to broaden this finding we designed a series of experiments to investigate the interaction of 2-D scale and 3-D structure on our perception of 3-D shape. We present a series of experiments where field of view, 3-D object complexity, 2-D image resolution, viewing orientation, and subject matter of the stimulus are manipulated. On each trial, observers indicated if the depicted objects appeared to be 2-D or 3-D. Results for face stimuli are similar to Pelli's, while more geometrically complex stimuli show a further interaction of the 3-D information with distance and image information. Complex objects need more image information to be seen as 3-D when close; however, as they are moved further away from the observer, there is a bias for seeing them as 3-D objects rather than 2-D images. Finally, image orientation, relative to the observer, shows little effect, suggesting the participation of higher-level processes in the determination of the 'solidness' of the depicted object. Thus, we show that the critical image resolution depends systematically on the geometric complexity of the object depicted.
