This paper presents an automatic multi-view selection approach for 3D reconstruction by means of a laser scanning vision system. It is realized based on the visual region of the laser scanning vision system. The candidate next best view (NBV) position is obtained by computing the unknown space area according to the limit visual region of the vision system. The final NBV position, which can acqu...

among abundant image denoising methods proposed so far, the use of patchbased algorithms have attracted a lot of attention from image processingcommunity. although these methods are very powerful in presentation of highquality results, the impact of human visual system (hvs) is ignored in sole of them.in this paper the human visual geometry is used in preparation of a new method forimage denois...

INTELLIGENT robots which manipulate objects using visual information have been studied and experimental models have already been developed in various laboratories. ~1-3) Generally the intelligent robot consists of the visual system, the handling system and the supervisory system that links these systems. The visual system and handling system are usually combined together as an open loop system....

This paper addresses a method of constructing a control system that realizes desired absolute hand position trajectory while walking. Controlling hand position in the absolute coordinate system with short delay while walking is a important function for realizing such motions as visual feedback reaching while walking, walking using handrail, and opening doors while walking. Based on previously d...

In this tutorial, knowledge-based visual measure methods with monocular vision system are investigated. The approaches of visual measure based on knowledge known in advance can be classified to four basic categories according to the types of knowledge, such as point position, line, size or shape knowledge, and motion knowledge. The principle for each category is shortly introduced. Furthermore,...

This paper describes work in progress on wearable computing configurations which provide audio and visual output based on the position and orientation of the user. We introduce the ‘eSleeve’ a wearable wrist computer with position and heading sensors combined with a user interface employing speech recognition and a small display. Applications described include searching a database of locations,...

This paper presents two vision-based interface systems. The first, Visual Screen, uses an inexpensive technique to transform an ordinary screen into a touch screen using an ordinary camera. The setup is easy: position a camera so it can see the whole screen. The system calibration involves the detection of the screen region in the image, which determines the projective mapping between the image...
