Abstract In crowded scenes, one of the most important issues is that heavily overlapped objects are hardly distinguished from each other since their pixels shared and visible occluded objects, which used to represent features, limited. this paper, a spatial pyramid convolutional shuffle (SPCS) module proposed extract refined information limited generate distinguishable representations for objec...

Accurate keypoint positioning is necessary for bottom-up multi-person pose estimation methods to handle scale variation and crowdedness. In this paper, we present DoubleHigherNet: a novel network learning scale-aware precise heatmap representation process using double high-resolution feature pyramids coarse-to-fine training. The two in DoubleHigherNet consists of 1/4 resolution higher-resolutio...

background: scenes depicting smoking are among the causes of smoking initiation in youth. the present study was the first in iran to collect some primary information regarding the presence of smoking scenes in movies and propagation of tobacco use. methods: this cross-sectional study was conducted by polling audience about smoking scenes in persian movies on theaters in 2011. data were collecte...

OBJECTIVES We determined whether crowding at emergency shelters is associated with a higher incidence of sleep disturbance among disaster evacuees and identified the minimum required personal space at shelters. DESIGN Retrospective review of medical charts. SETTING 30 shelter-based medical clinics in Ishinomaki, Japan, during the 46 days following the Great Eastern Japan Earthquake and Tsun...

The motion after-effect (MAE) persists in crowding conditions, i.e., when the adaptation direction cannot be reliably perceived. The MAE originating from complex moving patterns spreads into non-adapted sectors of a multi-sector adapting display (i.e., phantom MAE). In the present study we used global rotating patterns to measure the strength of the conventional and phantom MAEs in crowded and ...

Spatial crowding impairs conscious visual perception and object recognition in clutter.Short presentation times produce crowding in the normal fovea, in young participants and in uncorrected presbyopes ("aging eye"), measured as reduced visual acuity (VA). On the other hand, perceptual learning improves near VA in healthy young adults, in presbyopia, and in amblyopia. Here we aimed at exploring...
