Time 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 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 کاملAmodal completion and the perception of depth without binocular correspondence.
Half-occlusions and illusory contours have recently been used to show that depth can be perceived in the absence of binocular correspondence and that there is more to stereopsis than solving the correspondence problem. In the present study we show a new way for depth to be assigned in the absence of binocular correspondence, namely amodal completion. Although an occluder removed all possibility...
متن کاملTime course of amodal completion revealed by a shape discrimination task.
We measured the extent of amodal completion as a function of stimulus duration over the range of 15-210 msec, for both moving and stationary stimuli. Completion was assessed using a performance-based measure; a shape discrimination task that is easy if the stimulus is amodally completed and difficult if it is not. Specifically, participants judged whether an upright rectangle was longer horizon...
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...
