Grouping local directional signals into moving contours
We consider how local motion signals are combined to represent the movements of spatially extensive objects. A series of band-pass target dots, whose collective motion defined a moving contour, was positioned within a field of randomly moving noise dots. The visibility of the contours did not depend on the direction of movement relative to local contour orientation unless the contour was constr...
متن کاملVisual motion integration is mediated by directional ambiguities in local motion signals
The output of primary visual cortex (V1) is a piecemeal representation of the visual scene and the response of any one cell cannot unambiguously guide sensorimotor behavior. It remains unsolved how subsequent stages of cortical processing combine ("pool") these early visual signals into a coherent representation. We (Webb et al., 2007, 2011) have shown that responses of human observers on a poo...
متن کاملGrouping local orientation and direction signals to extract spatial contours: Empirical tests of “association field” models of contour integration
Over the last decade or so a great deal of psychophysical research has attempted to delineate the principles by which local orientations and motions are combined across space to facilitate the detection of simple spatial contours. This has led to the development of "association field" models of contour detection which suggest that the strength of linking between neighbouring elements in an imag...
متن کاملAutomatic Face Recognition via Local Directional Patterns
Automatic facial recognition has many potential applications in different areas of humancomputer interaction. However, they are not yet fully realized due to the lack of an effectivefacial feature descriptor. In this paper, we present a new appearance based feature descriptor,the local directional pattern (LDP), to represent facial geometry and analyze its performance inrecognition. An LDP feat...
متن کاملIntegration of contours: new insights.
Psychophysical, neurophysiological and anatomical research of the last few years has converged on a new explanation of how the components of a contour become integrated. Borrowing from the Gestalt rules of good continuation, this research suggests that components of a curved contour become integrated when the alignment follows specific rules. Here, we review some of the behavioral, anatomical a...
