Experience-Dependent Perceptual Grouping and Object-Based Attention
Attention can be allocated to objects as well as locations, even if the objects are partially occluded. A fundamental question concerns the nature of the ‘objects’ of this attention. Recent studies show that objects can be defined based on Gestalt grouping principles, or based on familiarity. The effects of both grouping and familiarity can be understood in terms of amore general hypothesis: th...
متن کاملSaliency-Guided Perceptual Grouping Using Motion Cues in Region-Based Artificial Visual Attention
Region-based artificial attention constitutes a framework for bio-inspired attentional processes on an intermediate abstraction level for the use in computer vision and mobile robotics. Segmentation algorithms produce regions of coherently colored pixels. These serve as proto-objects on which the attentional processes determine image portions of relevance. A single region—which not necessarily ...
متن کاملthe effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
assessment of the efficiency of s.p.g.c refineries using network dea
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
Contrast-sensitive perceptual grouping and object-based attention in the laminar circuits of primary visual cortex
Recent neurophysiological studies have shown that primary visual cortex, or V1, does more than passively process image features using the feedforward filters suggested by Hubel and Wiesel. It also uses horizontal interactions to group features preattentively into object representations, and feedback interactions to selectively attend to these groupings. All neocortical areas, including V1, are ...
