Collinearity improves alignment Response to Keeble and Hess (1998)
reported that collinear carrier orientation had no effect on the alignment of Gabor patches. This null conclusion, part of a broader paper on orientation effects, is not necessarily fully jus-tified––(a) we failed to replicate it, (b) it is not particularly well supported by their own data, (c) predictions of the effect suggest it is likely to be small, and (d) it is unwise, in view of accepted...
متن کاملCollinearity improves alignment in amblyopia as well as in normal vision
In normal vision, three contrast patches containing black and white bars are aligned more precisely when the bars are collinear across the patches [Popple, A., Polat, U., & Bonneh, Y. (2001). Collinear effects on 3-Gabor alignment as a function of spacing, orientation and detectability. Spatial Vision, 14(2), 139-150]. Normally, offsets between the bars in successive patches make the configurat...
متن کاملWithin-texture collinearity improves human texture segmentation
Spatial arrangement has been shown to facilitate both detection of a threshold target by collinear flankers and detection of smooth chains within random arrays of suprathreshold elements. Here, we investigate the effect of alignment between texture elements on orientation-based texture segmentation. Textures composed of Gabor elements were used in a figure-discrimination task. The degree of col...
متن کاملchainCleaner improves genome alignment specificity and sensitivity
Motivation Accurate alignments between entire genomes are crucial for comparative genomics. However, computing sensitive and accurate genome alignments is a challenging problem, complicated by genomic rearrangements. Results Here we present a fast approach, called chainCleaner, that improves the specificity in genome alignments by accurately detecting and removing local alignments that obscur...
متن کاملVisual perception of collinearity.
In a metrical space, there exists an intimate relation between collinearity and parallelity. In particular, in a Riemannian space collinearity is just a special case of parallelity. Is this true for visual space as well? We investigated the visual perception of collinearity by having subjects align two bars in the horizontal plane at eye height. The distances of the bars from the subject and th...
