Perceptual Similarity in Autism

Perceptual similarity in autism.

People with autism have consistently been found to outperform controls on visuo-spatial tasks such as block design, embedded figures, and visual search tasks. Plaisted, O'Riordan, and others (Bonnel et al., 2003; O'Riordan & Plaisted, 2001; O'Riordan, Plaisted, Driver, & Baron-Cohen, 2001; Plaisted, O'Riordan, & Baron-Cohen, 1998a, 1998b) have suggested that these findings might be explained in...

Perceptual texture similarity estimation

This thesis evaluates the ability of computational features to estimate perceptual texture similarity. In the first part of this thesis, we conducted two evaluation experiments on the ability of 51 computational feature sets to estimate perceptual texture similarity using two different evaluation methods, namely, pair-of-pairs based and retrieval based evaluations. These experiments compared th...

Perceptual image similarity experiments

In this paper, we study how human observers judge image similarity. To do so, we have conducted two psychophysical scaling experiments and have compared the results to two algorithmic image similarity metrics. For these experiments, we selected a set of 97 digitized photographic images which represent a range of semantic categories, viewing distances, and colors. We then used the two perceptual...

Perceptual Similarity and Conceptual Structure

Perceptual evaluation of music similarity

This paper presents an empirical method for assessing music similarity on a set of stimuli using triadic comparisons in a balanced incomplete block design. We first evaluated the consistency of subjects in their rankings and then the concordance across subjects. The concordance was also evaluated for different subject populations to assess the influence of experience of the subject with the mus...
