Abstract
Deconstructing the relief inversion effect: Contributors of the problem and its solutions
Highlights
We are developing full papers reporting the effects of each tested factor in detail, which would be beyond the scope of this short paper
Terrain reversal effect is a common and well-known illusion encountered in shaded relief maps and satellite imagery where the main depth cue is shading/shadows (Imhof, 1967; Bernabe-Poveda, Callejo, & Ballari, 2005; Saraf, Das, Agarwal, & Sundaram, 1996; Biland & Çöltekin, 2016; Çöltekin, Rautenbach, Coetzee, & Mokwena, 2018)
When the prior is violated, we see three-dimensional (3D) shapes ambiguously, or inverted; such that a valley looks like a ridge in a terrain representation and vice versa (Bernabé-Poveda, Sánchez-Ortega, & Çöltekin, 2011; Bernabé-Poveda & Çöltekin, 2014)
Summary
We are developing full papers reporting the effects of each tested factor in detail, which would be beyond the scope of this short paper. Terrain reversal ( known as relief inversion) effect is a common and well-known illusion encountered in shaded relief maps and satellite imagery where the main depth cue is shading/shadows (Imhof, 1967; Bernabe-Poveda, Callejo, & Ballari, 2005; Saraf, Das, Agarwal, & Sundaram, 1996; Biland & Çöltekin, 2016; Çöltekin, Rautenbach, Coetzee, & Mokwena, 2018). This illusion interferes with our perception of shape from shading (e.g., see Kleffner & Ramachandran, 1992; Prados & Faugeras, 2006).
