Visual Perception: Understanding Visual Cues to Depth
A new study shows that, in vision, object blur can be a more accurate depth cue than stereo disparity.
متن کاملReaching for visual cues to depth: the brain combines depth cues differently for motor control and perception.
Vision provides a number of cues about the three-dimensional (3D) layout of objects in a scene that could be used for planning and controlling goal-directed behaviors such as pointing, grasping, and placing objects. An emerging consensus from the perceptual work is that the visual brain is a near-optimal Bayesian estimator of object properties, for example, by integrating cues in a way that acc...
متن کاملVisual perception of planar orientation: dominance of static depth cues over motion cues
We measured the ability to report the tilt (direction of maximal slope) of a plane under monocular viewing conditions, from static depth cues (square grid patterns) and motion parallax (small rotations of the plane about a frontoparallel axis). These two cues were presented separately, or simultaneously. In the latter case they specified tilts that were either collinear (coherent case) or ortho...
متن کاملAdapting internal statistical models for interpreting visual cues to depth.
The informativeness of sensory cues depends critically on statistical regularities in the environment. However, statistical regularities vary between different object categories and environments. We asked whether and how the brain changes the prior assumptions about scene statistics used to interpret visual depth cues when stimulus statistics change. Subjects judged the slants of stereoscopical...
متن کاملLesions to right posterior parietal cortex impair visual depth perception from disparity but not motion cues
The posterior parietal cortex (PPC) is understood to be active when observers perceive three-dimensional (3D) structure. However, it is not clear how central this activity is in the construction of 3D spatial representations. Here, we examine whether PPC is essential for two aspects of visual depth perception by testing patients with lesions affecting this region. First, we measured subjects' a...
