A database related to the activities of the Liverpool vision assessment team was used to identify all children with vision impairment aged 0-16 years, resident in Liverpool, UK, on 1 April 1995. Prevalence rates were calculated for all children with vision impairment, and separately for two groups: those with uncomplicated vision impairment, and those with additional pathology. Visual tract pat...

In this paper we provide a broad survey of developments in active vision in robotic applications over the last 15 years. With increasing demand for robotic automation, research in this area has received much attention. Among the many factors that can be attributed to a high-performance robotic system, the planned sensing or acquisition of perceptions on the operating environment is a crucial co...

A novel active-vision system for 3-D object recognition was developed. The vision system combines object pre-marking and active sensing. Therein, an object is modeled by a few of its 2-D perspective (standard) views, each with a corresponding viewing axis defined by a marker placed on the object. The operation of the active-vision system is characterized by its off-line planning and on-line rec...

Good management begins with planning, and at the foundations of planning must lie an understanding of the nature of the institution: what its role is in society and how it goes about fulfilling that role. In my own institution, the Canadian Museum of Civilization (CMC) the driving vision of the Director, George MacDonald, was crucial to the project, during the '80s, to create a new museum respo...

PURPOSE OF THE STUDY To examine the documentation of sensory impairment in the electronic medical records (EMRs) of Veterans with both hearing and vision losses (dual sensory impairment [DSI]). DESIGN AND METHODS A retrospective chart review of the EMRs of 20 patients with DSI was conducted. Providers' documentation of the presence of sensory impairment, the use of assistive technology during...

The purpose of this study was to identify the key factors in implementing the organization's resource planning system in Chaharmahal and Bakhtiari Saderat Bank using theme analysis method. This research was a type of qualitative research that was done in an applied way. The research population consists of 15 experts and specialist in system implementation, resource planning in Chaharmahal and B...

This paper investigates the temporal dependencies of natural vision by measuring eye and hand movements while subjects made a sandwich. The phenomenon of change blindness suggests these temporal dependencies might be limited. Our observations are largely consistent with this, suggesting that much natural vision can be accomplished with "just-in-time" representations. However, we also observe se...

Physically-based simulation software is commonly used for developing and testing low-level robot control algorithms. In order to facilitate the development and evaluation of higher-level robot behaviors, broaderbased simulations are needed. Examples include software for simulating 3D vision, motion planning for obstacle avoidance, and integrating vision and planning. In addition to modeling the...

The authors tested whether the effects of the Ebbinghaus illusion on grasping are corrected during late phases of the movement. Surprisingly, the grasp aperture was corrected neither under no-vision (N = 52) nor under full-vision (N = 48) conditions. The authors show that previous reports of a correction (e.g., S. Glover & P. Dixon, 2002a) are due to 2 artifacts: (a) inclusion of time points at...

In this paper, a solution is presented for a robotic manipulation problem in industrial settings. The problem is sensing objects on a conveyor belt, identifying the target, planning and tracking an interception trajectory between end effector and the target. Such a problem could be formulated as combining object recognition, tracking and interception. For this purpose, we integrated a vision sy...
