Amodal completion and localization
In a three-line vernier acuity task, a central line was localized between two aligned line segments. Accuracy did not improve when the segments formed a unified amodally completed percept. In a two-line vernier acuity task, a line was localized below a target line placed next to a physically segmented flank stimulus. Shifts in mean points of subjective equality suggested that amodally completed...
متن کاملTime course of amodal completion in face perception
The visual system often automatically perceives partially occluded objects as whole and complete. This phenomenon is called amodal completion, but its mechanism is not fully understood. In the first experiment, we measured the psychophysical time course of face amodal completion using a performance-based method and found the amodal completion took place between 100 and 300 ms after stimulus ons...
متن کاملAmodal volume completion: 3D visual completion
This work considers the common problem of completing partially visible artifacts within a 3D scene. Human vision abilities to complete such artifacts are well studied within the realms of perceptual psychology. However, the psychological explanations for completion have received only limited application in the domain of 3D computer vision. Here, we examine prior work in this area of computer vi...
متن کاملComplete mergeability and amodal completion.
When image fragments are taken to correspond to the visible portions of a single occluded object, the object is said to 'amodally complete' behind the occluder. Kellman and Shipley (Kellman, P. J., & Shipley, T. F. (1991). A theory of visual interpolation in objective perception. Cognitive Psychology, 23, 144-221) argued that when the virtual contour extensions of such image fragments subtend a...
متن کاملAmodal completion in texture visual evoked potentials
Amodal completion refers to the phenomenological finding of perceiving partly occluded objects as continuing uninterrupted behind an occluder. The outlying problem is how the visual system processes such non-local stimuli because the known processes of early vision are spatially restricted operations which segregate local differences in the visual image, and little is known about their interact...
