ABSTRACT

The question of how to convey depth most effectively in a picture is a multifaceted problem, both because of potential limitations of the chosen medium (stereopsis? image motion?), and because “effectiveness” can be defined in various ways. Practical applications usually focus on “information transfer,” i.e., effective techniques for evoking recognition of implied depth relationships, but this issue depends on subjective judgments which are difficult to scale when stimuli are above threshold. Two new approaches to this question are proposed here which are based on alternative criteria for effectiveness.
