چکیده

Contour integration is a dynamical process which links oriented, local elements into the percept of a coherent contour. Detailed psychophysical studies have described the basic properties of this process. In particular, studies on a contourdetection paradigm where subjects have to find a continuous path of Gabor elements embedded in a background of randomly orientated Gabor elements have demonstrated the impact of several stimulus parameters on contour integration. For example, element distance, alignment of the elements relative to the contour path, or curvature of the contour path itself influence the saliency of a contour [1].

How ideal do macaque monkeys integrate contours?

In this contribution, we present a joint study combining psychophysical investigations with macaque monkeys and probabilistic modelling of contour integration. We study the detection of Sand U-shaped contours of aligned Gabor patches among a set of unaligned distracters. This approach allows to compare quantitatively the performance of monkeys with the performance predicted by a probabilistic m...

Contour Integration Models Predicting Human Behavior

Contour integration is believed to be a fundamental process in object recognition and image segmentation. However, its neuronal mechanisms are still not well understood. Psychophysical experiments showed that humans are remarkably efficient in integrating contours even if these are jittered or partially occluded. Therefore the brain requires a reliable algorithm for extracting contours from sti...

Contour Integration Based on Synchronization Mediated by Self-Organized Lateral Connections

Contour integration is believed to occur based on lateral interaction between neurons with similar orientation tuning. The exact neural mechanisms underlying such interactions, and their developmental origins, are not well understood. This paper suggests through computational simulations that synchronization mediated by patchy lateral connections, formed through input-driven self-organization, ...

Integration of form and motion within a generative model of visual cortex

One of the challenges faced by the visual system is integrating cues within and across processing streams for inferring scene properties and structure. This is particularly apparent in the inference of object motion, where psychophysical experiments have shown that integration of motion signals, distributed across space, must also be integrated with form cues. This has led several to conclude t...

Modelling the dynamics of motion integration with a new luminance-gated diffusion mechanism

The dynamics of motion integration show striking similarities when observed at neuronal, psychophysical, and oculomotor levels. Based on the inter-relation and complementary insights given by those dynamics, our goal was to test how basic mechanisms of dynamical cortical processing can be incorporated in a dynamical model to solve several aspects of 2D motion integration and segmentation. Our m...
