Active Vision Strategies in Predation
… affected by how it moves its eyes, known as active vision. Insects have immobile eyes but can direct their gaze by moving their heads and bodies. This thesis examines three predatory insects with different predatory strategies, to understand the extent to which active vision can be used in …

Feasibility of active vision for inspection of continuous concrete pipes.
… work to establish the feasibility of using active vision on a mobile robot to improve survey techniques for concrete and clay sewers of less than 1m diameter. Software and hardware components of a prototype mobile remote visual sensing system have been designed and developed. The active …

Active Vision for Object Recognition by Dynamically Fusing Eye-in-Hand Data
… is to investigate and implement novel computer vision techniques based on active vision, that dynamically manipulate cameras (mounted on autonomous robots) in order to better explore and understand the environment, as compared to static camera solutions. Such an active vision approach can help …

Development of an Active Vision System for the Remote Identification of Multiple Targets
This thesis introduces a centralized active vision system for the remote identification of multiple targets in applications where the targets may outnumber the active system resources. Design and implementation details of a modular active vision system are presented, from which a prototype has been …

Surveillance of Time-varying Geometry Objects using a Multi-camera Active-vision System
… Herein, it is proposed that a multi-camera active-vision system, which dynamically selects camera poses in real-time, be used to improve TVG action sensing performance by selecting camera views on-line for near-optimal sensing-task performance. Active vision for TVG objects requires an …

A Novel Method to Locate Targets Using Active Vision and Robotic Inertial Navigation Data
… that will use a combination of cheap, simple vision sensors and robot inertial navigation data in order to accurately measure the location of a target in real world coordinates. This thesis will first develop an accurate waypoint driving algorithm that will either use dead reckoning or GPS/ …

Active object recognition for 2D and 3D applications
Active object recognition provides a mechanism for selecting informative viewpoints to complete recognition tasks as quickly and accurately as possible. One can manipulate the position of the camera or the object of interest to obtain more useful information. This approach can improve the …

A Continuous-Time Nonlinear Observer for Estimating Structure from Motion from Omnidirectional Optic Flow
… local environment, a process known as <italic>active vision</italic>. This dissertation presents the development of a continuous-time formulated observer for estimating structure from motion that emulates the biological phenomenon of active vision. In an attempt to emulate the wide-field of …

Dynamic integration of depth cues for surface reconstruction from stereo images
… in the environment. This follows the paradigm of active vision, which implies a feedback mechanism to select physical sensory parameters in order to improve the quality of the derived results.

Exploiting object dynamics for recognition and control
… observations of an object. Considered are active vision systems that allow to steer the camera along predetermined trajectories, resulting in sweeps of ordered views of an object. For systems of this kind, a solution is presented that exploits the order relationship between successive …

Monocular and Binocular Visual Tracking
… of the most important applications of computer vision. Several tracking systems have been developed which either focus mainly on the tracking of targets moving on a plane, or attempt to reduce the 3-dimensional tracking problem to the tracking of a set of characteristic points of the target. …
