Perceptual Grouping Using Superpixels
Perceptual grouping plays a critical role in both human and computer vision. However, with the object categorization community’s preoccupation with object detection, interest in perceptual grouping has waned. The reason for this is clear: the object-independent, mid-level shape priors that form the basis of perceptual grouping are subsumed by the object-dependent, high-level shape priors define...
متن کاملThe popout in some conjunction searches is due to perceptual grouping.
The target in a visual search task usually pops out if it can be distinguished from its background on the basis of only one visual feature but not if the target represents a conjunction of two or more features. However, several recent reports suggest that in certain cases, search targets defined by a conjunction of two features also pop out. We have reinvestigated three pairs of such features t...
متن کاملPerceptual grouping, not emotion, accounts for search asymmetries with schematic faces.
Several different explanations have been proposed to account for the search asymmetry (SA) for angry schematic faces (i.e., the fact that an angry face target among friendly faces can be found faster than vice versa). The present study critically tested the perceptual grouping account, (a) that the SA is not due to emotional factors, but to perceptual differences that render angry faces more sa...
متن کاملPerceptual grouping determines haptic contextual modulation
Since the early phenomenological demonstrations of Gestalt principles, one of the major challenges of Gestalt psychology has been to quantify these principles. Here, we show that contextual modulation, i.e. the influence of context on target perception, can be used as a tool to quantify perceptual grouping in the haptic domain, similar to the visual domain. We investigated the influence of targ...
متن کاملElectromagnetic Models for Perceptual Grouping
The use of electromagnetic analogies for perceptual grouping of image primitives is presented. This approach assumes that grouping is a low-level, data-driven and global process, with all image tokens interacting in some way. Two computational models are introduced, which allow determination of proximity and directionality of image primitives. With the second model, prominent image features are...
