This paper describes an extension to a class of surface reconstruction algorithms based on the minimization of variation of curvature, the so-called curvature consistency framework. It deals explicitly with the problem of localizing surface discontinuities, which was one of the shortcomings of the original work. Inter-pixel interactions during the variational relaxation based smoothing process ...

Sinai et al (1998 Nature 395 497-500) showed that less distance is perceived along a ground surface that spans two differently textured regions than along a surface that is uniformly textured. We examined the effect of texture continuity on judged distance using computer-generated displays of simulated surfaces in five experiments. Discontinuities were produced by using different textures, the ...

Our previous studies in depth perception (Meng & Sedgwick, 2001) have supported a surface representation of 3-D layout. In such a representation, space is defined by surfaces, and distance is specified along those surfaces rather than through empty space (Alhazen, 1989, p. 155; Gibson, 1950, p. 6; Sinai, Ooi, & He, 1998; reviewed in Sedgwick, 2001). There is increasing evidence that visible sur...
