1. Coupled computations of three-dimensional shape and material

    Current Biology 25(6) (2015) PMID 25784037

    Retinal image structure arises from the interaction between a surface's three-dimensional shape, its reflectance and transmittance properties, and the surrounding light field. Any local image structure can be generated by an infinite number of different combinations of surface properties, which ...
  2. How shape from contours affects shape from shading.

    Vision Research 103:1 (2014) PMID 25130407

    The spatial pattern of reflected light carries detailed but ambiguous information about 3D shapes of illuminated objects. A little studied factor that affects the perceived 3D relief of 2D shaded figures is the shape of their contours. An experiment is reported in which 102 subjects matched twel...
  3. The roles of image decomposition and edge curvature in the ‘snake’ lightness illusion

    Vision Research 97:1 (2014)

  4. The roles of image decomposition and edge curvature in the 'snake' lightness illusion.

    Vision Research 97:1 (2014) PMID 24508808

    The snake illusion is an effect in which the lightness of target patches is strongly affected by the luminance of remote patches. One explanation is that such images are decomposed into a pattern of illumination and a pattern of reflectance, involving a classification of luminance edges into ill...

  7. Evaluation of single-point sampling strategies for the estimation of moclobemide exposure in depressive patients.

    The Journal of clinical pharmacology and new drugs 51(5):661 (2011) PMID 20495135

    Because moclobemide pharmacokinetics vary considerably among individuals, monitoring of plasma concentrations lends insight into its pharmacokinetic behavior and enhances its rational use in clinical practice. The aim of this study was to evaluate whether single concentration-time points could a...

  9. Adjacency and surroundedness in the depth effect on lightness.

    Journal of Vision 10(9):12 (2010) PMID 21057137

    Using two perpendicular planes, one brightly and one dimly illuminated, A. L. Gilchrist (1977) showed that target lightness can change nearly from black to white by changing its perceived spatial position, with no change in the retinal image, if the target has an adjacent coplanar neighbor in ea...

  11. Moclobemide monotherapy vs. combined therapy with valproic acid or carbamazepine in depressive patients: a pharmacokinetic interaction study.

    British Journal of Clinical Pharmacology 67(2):199 (2009) PMID 19076986 PMCID PMC2670377

    Moclobemide (MCB) undergoes extensive both presystemic and systemic metabolism that can be affected by concomitant drugs. Valproic acid (VPA) and carbamazepine (CBZ) have been found to interact with psychotropic medications of all classes and many other drugs; VPA acts as a broad-spectrum inhibi...

  13. The effect of face eccentricity on the perception of gaze direction.

    Perception 38(1):109 (2009) PMID 19323141

    The perception of a looker's gaze direction depends not only on iris eccentricity (the position of the looker's irises within the sclera) but also on the orientation of the lookers' head. One among several potential cues of head orientation is face eccentricity, the position of the inner feature...

  15. The effect of the observer vantage point on perceived distortions in linear perspective images.

    Attention, Perception & Psychophysics 71(1):183 (2009) PMID 19304608

    Some features of linear perspective images may look distorted. Such distortions appear in two drawings by Jan Vredeman de Vries involving perceived elliptical, instead of circular, pillars and tilted, instead of upright, columns. Distortions may be due to factors intrinsic to the images, such as...

  17. Is pictorial perception robust? The effect of the observer vantage point on the perceived depth structure of linear-perspective images.

    Perception 37(1):106 (2008) PMID 18399251

    Every image of a scene produced in accord with the rules of linear perspective has an associated projection centre. Only if observed from that position does the image provide the stimulus which is equivalent to the one provided by the original scene. According to the perspective-transformation h...

  19. Geometrical basis of perception of gaze direction.

    Vision Research 46(21):3549 (2006) PMID 16904157

    Perception of gaze direction depends not only on the position of the irises within the looker's eyes but also on the orientation of the looker's head. A simple analysis of the geometry of gaze direction predicts this dependence. This analysis is applied to explain the Wollaston effect, the Mona ...
