Graph-based Visual Saliency Model using Background Color
Visual saliency is a cognitive psychology concept that makes some stimuli of a scene stand out relative to their neighbors and attract our attention. Computing visual saliency is a topic of recent interest. Here, we propose a graph-based method for saliency detection, which contains three stages: pre-processing, initial saliency detection and final saliency detection. The initial saliency map i...
متن کاملSearching for camouflaged targets: Effects of target-background similarity on visual search
Do observers search for camouflaged targets by looking through the distractors or by scrutinizing the target-similar background? In four experiments observers searched for toy targets among distractors under varying set size and target-background similarity (TBS) conditions. Manual errors and RTs increased with TBS, although search slopes did not significantly differ. Eye movement analyses reve...
متن کاملthe effects of previewing and providing background knowledge on iranian university efl learners’ comprehension of literary and academic texts
abstract poor reading comprehension can result in failure in using references, benefiting from professional gatherings and resources, keeping up with the growing body of knowledge in the virtual world of the internet, and failing to achieve in efl programs. the purpose of the present quasi-experimental study was to explore the effects of background knowledge and previewing narrative and expos...
15 صفحه اولNon-uniformity - Some Background
The conditional result we saw last time does much more than that. If we have a language in the uniform class E not in the non-uniform class SIZE(s(n)) then a PRG exists. I.e., there is a way to systematically replace random bits with pseudorandom bits such that no BPP algorithm will (substantially) notice the difference. Thus, not only it shows that all languages in BPP are in fact in P (or wha...
متن کاملThe effect of background color on asymmetries in color search.
Many previous studies have shown that background color affects the discriminability and appearance of color stimuli. However, research on visual search has not typically considered the role that the background may play. Rosenholtz (2001a) has suggested that color search asymmetries result from the relationship between the stimuli and the background. Here we test the hypothesis that background c...
