A Model of Saliency-Based Visual Attention
        for Rapid Scene Analysis
           Laurent Itti, Christof Koch, and Ernst Niebur

Abstract—A visual attention system, inspired by the behavior and the
neuronal architecture of the early primate visual system, is presented.
Multiscale image features are combined into a single topographical
saliency map. A dynamical neural network then selects attended
locations in order of decreasing saliency. The system breaks down the
complex problem of scene understanding by rapidly selecting, in a
computationally efficient manner, conspicuous locations to be analyzed
in detail.
Index Terms—Visual attention, scene analysis, feature extraction,
target detection, visual search.

PRIMATES have a remarkable ability to interpret complex scenes in
real time, despite the limited speed of the neuronal hardware avail-

Fig. 4. The architecture of the hierarchical neural network used in the visual perception/concept simulation in the GNOSYS brain. There is a hierarchy of modules simulating
the known hierarchy of the ventral route of V1 ? V2 ? V4 ? TEO ? TE ? PFC(IFG) in the human brain. The dorsal route is represented by V1 ? V5 ? LIP ? FEF, with a
lateral connectivity from LIP to V4 to allow for linking the spatial position of an object with its identity (as known in the human brain). There are two sets of sigma–pi weights,
one from TPJ in the ventral stream which acts on the inputs from V2 to V4, the other from SPL which acts on the V5 to LIP inputs. This allows for the multiplicative control of
attention.

Multiscale image features are combined into a single topographical saliency map. A dynamical neural network then selects attended locations in order of decreasing saliency. The system breaks down the complex problem of scene understanding by rapidly selecting, in a computationally efficient manner, conspicuous locations to be analyzed in detail. Index Terms—Visual attention, scene analysis, feature extraction, target detection, visual search. ———————— F ———————— 1 INTRODUCTION PRIMATES have a remarkable ability to interpret complex scenes in real time, despite the limited speed of the neuronal hardware avail- Fig. 1. General architecture of the model. able for such tasks. Intermediate and higher visual processes appear to select a subset of the available sensory information before further processing [1], most likely to reduce the complexity of scene analysis bottom-up saliency and does not require any top-down guidance [2]. This selection appears to be implemented in the form of a spa- to shift attention. This framework provides a massively parallel tially circumscribed region of the visual field, the so-called “focus of method for the fast selection of a small number of interesting im- attention,” which scans the scene both in a rapid, bottom-up, sali- age locations to be analyzed by more complex and time- ency-driven, and task-independent manner as well as in a slower, consuming object-recognition processes. Extending this approach top-down, volition-controlled, and task-dependent manner [2]. in “guided-search,” feedback from higher cortical areas (e.g., Models of attention include “dynamic routing” models, in knowledge about targets to be found) was used to weight the im-

The architecture of the hierarchical neural network used in the visual perception/concept simulation in the GNOSYS brain. There is a hierarchy of modules simulating the known hierarchy of the ventral route of V1 ? V2 ? V4 ? TEO ? TE ? PFC(IFG) in the human brain. The dorsal route is represented by V1 ? V5 ? LIP ? FEF, with a lateral connectivity from LIP to V4 to allow for linking the spatial position of an object with its identity (as known in the human brain). There are two sets of sigma–pi weights, one from TPJ in the ventral stream which acts on the inputs from V2 to V4, the other from SPL which acts on the V5 to LIP inputs. This allows for the multiplicative control of attention.
