Part boundaries alter the perception of transparency

Article Abstract:

The perception of transparency results from the formation of visual objects and their parts in an early human vision process. Gestalt figural conditions for the perception of transparency can be refined by using the genericity principle, the minima rule and a part-salience rule. The experiments conducted reveal that human vision constructs visual objects in a highly coordinated manner. When central parts of transparent displays are seen as a one-part object, they are perceived as being transparent and with uniform reflectance. However, if they are seen as two parts, they are perceived as opaque and with different reflectances.

Varieties of binocular interaction in human vision

Article Abstract:

Models of underlying processing architectures in human performance linked to theories of cognition and perception frequently consist of elementary operations, filters and processing stages that can be arranged in series or parallel. However, a variety of analytical tools have been developed that differentiate serial, parallel and hybrid processing architectures and are related to reaction times. State-of-the-art stochastic real time modeling techniques are applied to binocular interactions in human vision with a focus on interactions between ON/OFF pathways. Results are discussed.

Transsaccadic memory and integration during real-world object perception

Article Abstract:

Veridical representations of object contour cannot be reliably retained and integrated across a saccade. Using a same/different approach in probing transsaccadic memory, Experiment 1 has discovered that object contour detection across a saccade is unreliable. Experiment 2, which examined transsaccadic integration in an object-naming task, has found out that a change in visible contour does not affect the integration process.
