A surveillance system combining peripheral and foveated motion tracking
نویسندگان
چکیده
In this paper we describe a surveillance system made up of a fixed camera and a binocular active vision system. The fixed camera is used to provide the system with peripheral motion detection capabilities. The binocular active system is used to track in 3D and reconstruct the trajectories of specific targets. Both are fully integrated and the redundancy is exploited to achieve a higher degree of robustness in detecting and tracking intruders.

Mixed Scale Motion Recovery Using Guidable Cameras
Captured human motion is widely used by the medical, surveillance, and entertainment industries. In these fields, many interesting motions occur at mixed scales. Subtle localized motion often occurs together with long range movements. One of the chief challenges in recovering these motions is to obtain high resolution imagery suitable for resolving small details, while simultaneously increasing...
متن کاملA Foveated Silicon Retina for Two-Dimensional Tracking
A silicon retina chip with a central foveal region for smooth-pursuit tracking and a peripheral region for saccadic target acquisition is presented. The foveal region contains a 9 x 9 dense array of large dynamic range photoreceptors and edge detectors. Two-dimensional direction of foveal motion is computed outside the imaging array. The peripheral region contains a sparse array of 19 x 17 simi...
متن کاملFoveated active tracking with redundant 2D motion parameters
This work presents a real-time active vision tracking system based on log-polar image motion estimation with 2D geometric deformation models. We present a very efficient parametric motion estimation method, where most computation can be done offline. We propose a redundant parameterization for the geometric deformations, which improve the convergence range of the algorithm. A foveated image rep...
متن کاملFoveated observation of shape and motion
Robotic navigation and interaction frequently require that the shape and motion of external objects and events be observed. Many interesting events occur at mixed scales. Subtle localized shape and motion often occurs together with long range movements. One of the chief challenges in recovering these events is to obtain high resolution imagery suitable for resolving small details, while simulta...
متن کاملPre-Attentive Face Detection for Foveated Wide-Field Surveillance
Conventional surveillance sensors suffer from an unavoidable tradeoff between image resolution and field of view. This problem may be overcome by combining a fixed, preattentive, low-resolution wide-field camera with a shiftable, attentive, high-resolution narrow-field camera. Here we present techniques for orienting the attentive camera to faces detected in the pre-attentive wide-field image s...
