Transparency and Temporal Integration
نویسنده
چکیده
Perceptual transparency requires local same-polarity X-junctions, which can also be generated by temporal integration under natural dynamic conditions. In this study, segmentation performance and target appearance were measured for a uniform gray target embedded in a random-dot frame presented with a temporally adjacent mask. Although static cues for both segmentation and transparency were unavailable, transparency was observed only when collinear same-polarity edges reduced backward masking, in both the fovea and the perifovea. These results suggest that the visual system has a common underlying mechanism for rapid segmentation and transparency, which utilizes same-polarity X-junctions generated by temporal integration.

Proper integration time of polarization signals of internetwork regions using Sunrise/IMaX data
Distribution of magnetic fields in the quiet-Sun internetwork areas has been affected by weak polarization (in particular Stokes Q and U) signals. To improve the signal-to-noise ratio (SNR) of the weak polarization signals, several approaches, including temporal integrations, have been proposed in the literature. In this study, we aim to investigate a proper temporal-integration time with which...
متن کاملA Novel Method for Measuring the Quality of Temporal Integration in Public Transport Systems
Temporal coordination of services, as a crucial aspect of integration in public transport systems, has always been a big concern for transit planners and schedulers. One of the major issues in the way of coordinating transit services is the lack of a robust measure of effectiveness for assessing the quality of temporal coordination in public transport systems. Even though the network-wide summa...

متن کاملAttitudes of Anatomy Faculties in Medical Schools toward Horizontal Integration of Courses on Anatomical Sciences
Introduction: Theoretical courses on anatomical sciences are taught through integrative or regional approaches. It seems that integration helps teachers to convey the materials better to medical students, especially during their clinical stage. Therefore, we decided to study the viewpoints of faculty members of anatomy department in medical universities of Iran toward the horizontal integration...
