Results of investigation of face detection algorithms in the video sequences are presented in the paper. The recordings were made with a miniature industrial USB camera in real conditions met in three bank operating rooms. The aim of the experiments was to check the practical usability of the face detection method in the biometric bank client verification system. The main assumption was to provide...
A hardware and software solution for guitar string vibration measurement by fast cameras is described. Orthogonal setup for 3D image acquisition is proposed capable to capture several thousand image frames per second. Dedicated image processing algorithm was developed and described in the paper, aimed at tracking the movement of some selected points along the string. Fast and accurate tracking results...
A novel, multimodal approach for automatic detection of abduction of a protected individual, employing dedicated personal protection device and a city monitoring system is proposed and overviewed. The solution is based on combining four modalities (signals coming from: Bluetooth, fixed and PTZ cameras, thermal camera, acoustic sensors). The Bluetooth signal is used continuously to monitor the protected...
A demonstrator of traffic events detector based on the multimodal analysis of audio and video signals is described. The subsystem is a part of smart surveillance applications. It uses surveillance cameras and microphones as the data source. The algorithms employed to the analysis of data - sound event recognition and video analytics, are explained. Results of the multimodal analysis of recordings...
A scent emitting multimodal computer interface is an important supplement of the polysensoric stimulation process. Such stimulation plays an essential role in education and therapy in children with developmental disorders (e.g. in the case of autism or ADHD). The interface engineered may be a part of the equipment of the so-called world experience rooms but can also be used separately, therefore enhancing...
This paper presents an algorithm for lip movement tracking and lip gesture recognition for the purpose of the multimodal human-computer interface (HCI) called LipMouse. This solution allows a user to work on a computer using movement and gesture made by his/her mouths only and is especially useful for severely disabled and paralyzed people. User face images are captured with a standard webcam. Face...
Development of the computer based system for strabismus and amblyopia therapy is discussed in the paper. In the case of amblyopia or `lazy-eye' syndrome, the therapy is typically conducted in two ways: by wearing a patch over the non-amblyopic eye for several hours per day or blurring the vision in the good eye with penalizing drops or with extra power in the glasses. The disadvantage of this types...
In this paper a discussion on the design and development of the graphical user interface (GUI) dedicated to Parkinson's Disease (PD) patients is presented. The interface is intended for a group of PD patients with less severe motor symptoms, who are living at their home independently or with help of a caregiver. The GUI is designed to enable an interaction for the non-computer literate PD patients...
Kalman filters were used for establishing relations between objects moving in video frames to the real moving objects under analysis. As a result of applying some popular methods of moving objects detection, the objects were represented by rectangles. A two-dimensional colour histogram based on a chromatic space was used for each object in experiments. The objects coupling with adequate regions including...
A concept and an implementation of a novel dynamic noise maps visualization tool is presented in this paper. The principal aim of the project is described. The first part depicts general features of the tool. The main focus is put on presenting the innovative features of the dynamic noise maps visualization tool in comparison to the commonly used solutions. The software components applied are briefly...
The paper presents application of cavity enhanced absorption spectroscopy (CEAS) technique for nitrogen dioxide (NO2) detection. The setup includes the resonance optical cavity, build with spherical and high reflectance mirrors. As a light source a pulsed blue diode laser is used (414 nm). The signal is registered by a photomultiplier connected to the digital oscilloscope.
The paper presents a part of an advanced system for railway and road traffic monitoring in metropolitan areas utilizing analyses of sound, vision and air pollution based on a ubiquitous computing approach. This system is a functional part of a more complex solution designed for environmental monitoring in cities. The system consists of many autonomous, universal measuring units and a multimedia server,...
This document describes the methodology of creating semantically-enriched multimedia mobile services using tools and service enablers provided by the DeSyME project. A brief introduction to the semantic Web is presented along with the explanation of its relation to the subject of Web services. Next, the description of the DeSyME framework is included. Finally, examples of multimedia mobile services...
