It is necessary to precisely measure pose (position and orientation) of a user in order to realize an augmented reality (AR) system with a wearable computer. One of major methods for measuring user’s pose in AR is visual marker-based approach which calculates them by recognizing markers pasted up on the ceilings or walls. The method needs 3D pose information of visual markers in advance. Howeve...

The use of material transfer units constructed from AGVs and robot manipulators is becoming popular in production lines with small production volumes and periods. This new material transfer unit is also called a mobile robot, which can quickly adapt to the change of the factory loyout. A mobile robot is sufficiently mobile that it can very flexibly perform tasks in the production line. A guidan...

introduction: it is recommended that the physician apply at least a semi-quantitative segmental scoring system in myocardial perfusion spect.  we aimed to assess the agreement between automated semi-quantitative analysis using qps (quantitative perfusion spect) software and visual approach for calculation of summed stress  score (sss), summed rest score (srs) and summed difference score (sds). ...

Servo applications (regulation and tracking) are an important class of tasks for robots. Robustness in a servo controller must be guaranteed when the robot manipulator operates in an uncertain environment to ensure the stability and performance in the presence of uncertain robot manipulator dynamics, objects to be manipulated by the robot, and obstacles to be avoid. Also, robots must have sensi...

Visual form analysis is fundamental to shape perception and likely plays a central role in perception of more complex dynamic shapes, such as moving objects or biological motion. Two primary form-based cues serve to represent the overall shape of an object: the spatial position and the orientation of locations along the boundary of the object. However, it is unclear how the visual system integr...

Small movements of a viewer relative to the surrounding scene induce deformations in the shape and detail of the projected image. This paper will consider the problem of using these deformations to provide visual feedback on the current position of the viewer relative to the scene. The implementation calculates the transformations that occur due to small movements around the current position. I...

This paper investigates passivity-based visual feedback pose regulation whose goal is to control a vision camera pose so that it reaches a desirable configuration relative to a moving target object. For this purpose, we present a novel visual feedback estimation/control structure including a vision-based observer called visual motion observer under the assumption that a pattern of the target mo...

Detecting the threats of the external obstacles to the power lines can ensure the stability of the power system. Inspired by the attention mechanism and binocular vision of human visual system, an intelligent power line inspection system is presented in this paper. Human visual attention mechanism in this intelligent inspection system is used to detect and track power lines in image sequences a...
