The relation between visual perception and the recorded image is discussed in this chapter, emphasising the historical growth of the understanding of depth perception and its visual cues. The stereoscopic principle is explained in detail, and figures are given for comfortable viewing of stereoscopic images.

Twenty male and five female undergraduates were assessed in a study designed to test for three dimensional pictorial perception in a Papua New Guinea sample. A version of Hudson's (1960) and Deregowski's (1968) test stimuli was used; the stimuli were slightly modified to make them culturally appropriate. The major result of the study was a finding of consistent sex differences in pictorial depth perception. Males tended to perceive three dimensionally while females tended to perceive two dimensionally.

Pictorial space is the 3-D impression that one obtains when looking ‘into’ a 2-D picture. One is aware of 3-D ‘opaque’ objects. ‘Pictorial reliefs’ are the surfaces of such pictorial objects in ‘pictorial space’. Photographs (or any pictures) do in no way fully specify physical scenes. Rather, any photograph is compatible with an infinite number of possible scenes that may be called ‘metameric scenes’. If pictorial relief is one of these metameric scenes, the response may be considered ‘veridical’. The conventional usage is more restrictive and is indeed inconsistent. Thus the observer has much freedom in arriving at such a ‘veridical’ response. To address this ambiguity, we determined the pictorial reliefs for eight observers, six pictures, and two psychophysical methods. We used ‘methods of cross-sections’ to operationalise pictorial reliefs. We find that linear regression of the depths of relief at corresponding locations in the picture for different observers often lead to very low (even insignificant) R2s. Thus the responses are idiosyncratic to a large degree. Perhaps surprisingly, we also observed that multiple regression of depth and picture coordinates at corresponding locations often lead to very high R2s. Often R2s increased from insignificant up to almost 1. Apparently, to a large extent ‘depth’ is irrelevant as a psychophysical variable, in the sense that it does not uniquely account for the relation of the response to the pictorial structure. This clearly runs counter to the bulk of the literature on pictorial ‘depth perception’. The invariant core of interindividual perception proves to be of an ‘affine’ rather than a Euclidean nature; that is to say, ‘pictorial space’ is not simply the picture plane augmented with a depth dimension.

Cue Processing

The FIVIS simulator system addresses the classical visual and acoustical cues as well as vestibular and further physiological cues. Sensory feedback from skin, muscles, and joints are integrated within this virtual reality visualization environment. By doing this it allows for simulating otherwise dangerous traffic situations in a controlled laboratory environment. The system has been successfully applied for road safety education applications of school children. In further research studies it is applied to perform multimedia perception experiments. It has been shown, that visual cues dominate by far the perception of visual depth in the majority of applications but the quality of depth perception might depend on the availability of other sensory information. This however, needs to be investigated in more detail in the future.
