SUNDAy: Saliency Using Natural Statistics for Dynamic Analysis of Scenes
The notion that novelty attracts attention is core to many accounts of visual saliency. However, a consensus has not been reached on how to best define novelty. Various interpretations of novelty lead to different bottom-up saliency models that have been proposed for static images and more recently for dynamic scenes. In previous work, we assumed that a basic goal of the visual system is to loc...
متن کاملAuditory Saliency Using Natural Statistics
In contrast to the wealth of saliency models in the vision literature, there is a relative paucity of models exploring auditory saliency. In this work, we integrate the approaches of (Kayser, Petkov, Lippert, & Logothetis, 2005) and (Zhang, Tong, Marks, Shan, & Cottrell, 2008) and propose a model of auditory saliency. The model combines the statistics of natural soundscapes and the recent past ...
متن کاملDisparity statistics in natural scenes.
Binocular disparity is the input to stereopsis, which is a very strong depth cue in humans. However, the distribution of binocular disparities in natural environments has not been quantitatively measured. In this study, we converted distances from accurate range maps of forest scenes and indoor scenes into the disparities that an observer would encounter, given an eye model and fixation distanc...
متن کاملLocal statistics in natural scenes predict the saliency of synthetic textures.
The visual system is challenged with extracting and representing behaviorally relevant information contained in natural inputs of great complexity and detail. This task begins in the sensory periphery: retinal receptive fields and circuits are matched to the first and second-order statistical structure of natural inputs. This matching enables the retina to remove stimulus components that are pr...
متن کاملSUN: Top-down saliency using natural statistics.
When people try to find particular objects in natural scenes they make extensive use of knowledge about how and where objects tend to appear in a scene. Although many forms of such "top-down" knowledge have been incorporated into saliency map models of visual search, surprisingly, the role of object appearance has been infrequently investigated. Here we present an appearance-based saliency mode...
