Search for a category target in clutter.
An airport security worker searching a suitcase for a weapon is engaging in an especially difficult search task: the target is not well-specified, it is not salient, and it is not predicted by its context. Under these conditions, search may proceed item-by-item. In the experiment reported here we tested whether the items for this form of search are whole familiar objects. Our displays were comp...

15 صفحه اولVisual search in clutter
Detecting a target in clutter is particularly difficult because the observer must monitor many potential locations to find the target, and because the clutter itself might mask the target. To investigate whether contemporary models of search can account for visual search in clutter, we measured the detection of an oblique string of five aligned dots presented at an unknown location as a functio...

We investigate the existence of some large sets of size nine. The large set $LS[9](2,5,29)$ is constructed and existence of the family $LS[9](2,5,27l+j)$ for $lgeq 1, 2leq j
متن کاملA scale invariant measure of clutter.
We propose a measure of clutter for real images that can be used to predict search times. This measure uses an efficient segmentation algorithm (P. Felzenszwalb & D. Huttenlocher, 2004) to count the number of regions in an image. This number is not uniquely defined, however, because it varies with the scale of segmentation. The relationship between the number of regions and the scale of segment...
