This paper presents the implementation in the Matlab/Simulink environment of an application for measuring distances using a video camera. Some of the advantages of using image processing as a method of measurement and of the Matlab for designing de application. The principles that where use to obtain de distance calculated where presented. Also the steps of the application implementation in Simulink...
Remote patient monitoring can improve the quality of life of elderly and impaired people, while reducing the costs. Among the most interesting technologies being investigated, computer vision has proved to be very effective in several important scenarios in which conventional sensors fail or are impractical. We propose a computer vision-based wireless sensor system for people remote tracking and monitoring...
Mobile navigation applications are the ones that must be tested in real environment in order to show their usability problems. Preparation of the study in real environment is complex issue and so is the analysis of the collected data from such study. Therefore we performed usability study of mobile navigation application for visually impaired users and implemented a set of visualization plugins for...
This paper presents image-based finger pose measurement for hand user interface. The aim of this measurement technique is to make a better user interface enabling three dimensional operation by hand. The measurement technique uses stereo vision, and approximates the hand motion based on anatomical constraints. Distinctive feature of the measurement technique is usage of ring markers, which enable...
An intelligent robot has been developed which understands the goal a user wants to be performed, recognizes its environment, develops strategies to execute the goal and operates autonomously. By means of a speech recognition sensor the robot listens to a spoken command and derives the goal a user wants the robot to perform, i.e. to bring a specific object. Next, the robot uses its smart camera and...
For various applications, such as object recognition or tracking and especially when the object is partly occluded or articulated as in human-machine-interaction scenarios, 3D information is crucial for the robustness of the application. Recently sensor had been developed that acquire distance information based Time-of-Flight (ToF) principle and for which distance errors based on different causes...
Nowadays, interaction represents an attractive approach for deploying new forms of entertainment and art. Towards this aim, novel technologies can make possible advanced concepts of interaction, hence supporting complicated application scenarios. In this work, an interactive audiovisual installation is presented, which aims to make the participant interact with the stars in the space. Human gesture...
The paper presents a prototype of a system which can be used as a therapeutic and educational tool for children with developmental problems. Natural body movements and gestures are used in the system to interact with virtual objects displayed on the screen. Nowadays such systems can be easily built with the use of widely available free software tools for both graphical and vision applications. Such...
This paper introduces an embedded architecture and the low-level video processing algorithms developed for an intelligent node that is a part of a distributed intelligent sensory network for surveillance purposes. In this paper, details of the architecture developed for this node are given, together with the low-level video processing algorithms used, as well as the results obtained after their implementation...
