Balas, and Livia Ilie ---------- Abstract Vision is an active process: We repeatedly move our eyes to seek out objects of interest and explore our environment. Visual search experiments capture aspects of this process, by having subjects look for a target within a background of distractors. Search speed often correlates with target–distractor discriminability; search is faster when the target and distractors look quite different. However, the… Ruth Rosenholtz publications Sun, 22 Apr 2012 14:34:06 -0400 http://persci.mit.edu/home?rev=1335119249&do=diff * Publications * Research * Gallery * Contact ---------- Principal Investigators * Ted Adelson * Ruth Rosenholtz Postdoctoral Scholars * Jie Huang * Bei Xiao Graduate Students * Krista Ehinger * Xiaodan(Stella) Jia * Phillip Isola * Alvin Raj * Nathaniel Twarog * Xuetao Zhang * Derya Akkaynak Yellin Ruth Rosenholtz Sun, 22 Apr 2012 14:27:29 -0400 http://persci.mit.edu/publications/textureeccv00?rev=1334937551&do=diff Ruth Rosenholtz ---------- Abstract Recent human vision research suggests modelling preattentive texture segmentation by taking a set of feature samples from a local region on each side of a hypothesized edge, and then performing standard statistical tests to determine if the two samples differ significantly in their mean or variance. If the difference is significant at a specified level of confidence, a human observer will tend to pre-attentively see a texture edge at that location.

Palmer, C. T. Ames, & D. T. Lindsey, 1993). In Experiment 1, participants searched for a 0° line among distractors at (a) 30°; (b) 1/3 at 30°, 2/3 at 50°; ( c) 1/3 at 30°, 50°, and 70°; (d) 1/3 at 30°, 2/3 at 70°. The SDT model predicts improved performance in the more heterogeneous conditions, as some distractors are more discriminable from the target… Ruth Rosenholtz publications Fri, 20 Apr 2012 11:56:01 -0400 http://persci.mit.edu/publications/earlyselect12?rev=1334936480&do=diff Ruth Rosenholtz, Jie Huang, and Krista A. Ehinger ---------- Abstract According to common wisdom in the field of visual perception, top-down selective attention is required in order to bind features into objects. In this view, even simple tasks, such as distinguishing a rotated T from a rotated L, require selective attention since they require feature binding. Selective attention, in turn, is commonly conceived as involving volition, intention, and at least implicitly, awareness. There is so… Ruth Rosenholtz publications Fri, 20 Apr 2012 11:41:20 -0400 http://persci.mit.edu/publications/qmf_coring86?rev=1334935796&do=diff Ruth Rosenholtz publications Fri, 20 Apr 2012 11:29:56 -0400 http://persci.mit.edu/publications/robust95?rev=1334935711&do=diff Ruth Rosenholtz publications Fri, 20 Apr 2012 11:28:31 -0400 http://persci.mit.edu/publications/texturevr97?rev=1334935622&do=diff Ruth Rosenholtz publications Fri, 20 Apr 2012 11:27:02 -0400 http://persci.mit.edu/publications/textureijcv97?rev=1334935579&do=diff Ruth Rosenholtz publications Fri, 20 Apr 2012 11:26:19 -0400 http://persci.mit.edu/publications/saliencyvr99?rev=1334935491&do=diff Ruth Rosenholtz publications Fri, 20 Apr 2012 11:24:51 -0400 http://persci.mit.edu/publications/localtexture99?rev=1334935421&do=diff Ruth Rosenholtz publications Fri, 20 Apr 2012 11:23:41 -0400 http://persci.mit.edu/publications/popoutprism02?rev=1334935134&do=diff Ruth Rosenholtz publications Fri, 20 Apr 2012 11:18:54 -0400 http://persci.mit.edu/publications/websearch02?rev=1334935090&do=diff A.

These thumbnails combine the advantages of plain thumbnails and text summaries to provide consistent performance on a variety of tasks. We conducted a study in which participants used three different types of summaries (enhanced thumbnails, plain thumbnails, and text summaries) to search Web pages to find several different types … Ruth Rosenholtz publications Fri, 20 Apr 2012 11:18:10 -0400 http://persci.mit.edu/publications/halo03?rev=1334935028&do=diff Ruth Rosenholtz publications Fri, 20 Apr 2012 11:17:08 -0400
