This paper describes an equipment setup and motion control strategy for automated visual mapping of steep underwater walls using a Remotely Operated Vehicle (ROV) equipped with a horizontally facing DVL to provide vehicle velocity and distance measurements relative to the underwater wall. The still images recorded by the stereo cameras of the ROV are post-processed into a 3D photogrammetry model using...
In this paper the system for tracking of a moving speaker is reported. The system utilizes audio visual information acquired from a camera and microphones. Using the camera a face of a speaker is detected. Two pairs of microphones allow for estimation of direction of sound arrival using general cross-correlation method. The preliminary results of experiments are described.
The Ocean Observatories Initiative's (OOI) Cabled Array (CA) is delivering high-definition video data since August 2015 via fiber optic cable from a statically positioned SubC 1Cam HD (CAMHD) video camera, deployed at the Mushroom hydrothermal vent in the Axial Seamount Hydrothermal Expeditions (ASHES) Field off the coast of Oregon (lat 45° 56.0186′N, long 130° 00.8185′W, depth 1,542 m). Over 20 TB...
In the paper, we describe the extensions of the 3D-HEVC compression technology aimed at improved compression efficiency for multiview sequences acquired from arbitrarily located cameras. Our proposal refines the inter-view prediction by replacing the horizontal shifts with the true mapping in the 3D space. This implies changes in several coding tools, which we describe in details. The paper also reports...
This article studies the smoke and exhaust detection system that has been developed for monitoring exhaust gases to enforce environmental laws and regulations. In many highly populated countries the HSU (Hart ridge Smoke Unit) grade is used to impose penalties. In many cases, HSU values over 40 … 50 are leading to legal actions.
Automated manufacturing systems are becoming increasingly flexible in order to support a growing number of different products and product variations, as well as shortening lot sizes and product life cycles. Many manufacturing resource are already multi-purpose. But they are integrated in an automation infrastructure that may require significant effort to adapt. In this contribution, we present a system...
The availability of hardware devices, applications and external connectivity in our computers and smartphones opens a wide range of opportunities for developing intelligent systems. People with some kind of motor disability can take advantage of such systems with minimal cost, as there are diverse hardware components already available in standard consumer products. Research reported in this document...
The paper presents a laboratory Wind Turbine System (WTS) which is added to existing Hybrid Power System (HPS) along with other main components like Solar Panel, Battery System, Solar Charge controller and Inverter. The WTS is operated with a Motor along with integrated Frequency converter. The complete system is designed to be monitored and controlled over internet from remote location under the...
Incongruity between emotional experience and its outwardly expression is one of the prominent symptoms in schizophrenia. Though widely reported and used in clinical evaluation, this symptom is inadequately defined in the literature and may be confused with mere affect flattening. In this study we used structured-light depth camera and dedicated software to automatically measure facial activity of...
The rapid development of Internet of Things and the current capabilities of high performance embedded systems have made them more attractive for the replacement of human personnel in hazardous or tedious duties. One such application is for guarding certain areas, such as the entrance of a warehouse for example. The aim of this work is to design an autonomous embedded security system for surveillance...
Many painting software is available in the software industry. Each of them has its own pros and cons. One of the main disadvantages of these painting software is the need of accurate pointing devices. Here we introduce the Smart Paint, which is a gesture based painting software. It uses the hand movements for drawing. User doesn't need an external hardware pointing device to draw. Instead the different...
Given a series of overlapped images, it is possible to reconstruct camera position and orientation, as well as 3D coordinates of object in the images. Such method is known as Structure from Motion (SfM), which is currently implemented in various commercial and open source software. The first software commonly don't provide Sfm algorithm. While the latter software are commonly developed partially....
The study of historical monument needs a great care especially for the old object. Along with current technologies, allowing the object studied scanned in three dimensions. To make the objective achieved, the digital form of objects studied has almost become mandatory for simplicity of study and also variety of analysis. For various scale of objects that present everywhere, hardware and software equipment...
We have developed a screen sharing system to share contents between two persons, and applicable to one-to-one remote teaching. The screen of a PC at one side is shared with the screen of a tablet at the other side through the network to convey instructions from an operator to a collaborator. This system makes it possible to arbitrarily select a part of the screen of the PC at the operator side. The...
It is well known that the conventional ways to capture the light around us are limited and thus provide a limited user experience, notably in terms of parallax capabilities. As this has been preventing 3D systems to explode in the market, significant advances are emerging in terms of light capturing technologies among which is relevant to highlight the socalled light field cameras which capture a...
Pulse discharge in water, through its generation of chemical active species, has many applications such as cleaning water at reservoirs and lakes. In the study of discharge in water, applications and generation mechanisms have been studied in recent years. However, some mechanisms remain unclarified, particularly in the area of high repetition discharges. High repetition discharges result in an interesting...
The paper presents an analysis of a rowing technique and the participant's fatigue based on the handle's trajectory. The rowing was recorded with the use of Vicon motion capture. Seven non-rowers were participants in the research. 42 strokes were analysed in three phases of rowing. Two theses: (i) “handle trajectory indicates the fatigue while rowing” and (ii) “the rowing technique may be assessed...
This paper proposes an image-processing algorithm for register marker detection in a roll-to-roll (R2R) system. Recently, R2R systems have been receiving considerable international attention from researchers because of their ability to print electronic devices on flexible substrates. During such printing, an R2R system must adjust its printing position by continuously checking the positions of the...
In this paper we investigate the effectiveness of the interaction using eye tracking and electromyography. Smart glasses requires reliable interfaces for controlling the graphic content displayed directly in front of the user's eye. Presented research is related with the eGlasses project, which is focused on the development of an open platform in the form of multisensory electronic glasses and related...
As an excellent underwater biorobotics, robotic fish has got considerable development in recent decades. However the majority of researches assume that the flow field where the fish swims is a steady one, ignoring the fact that fish in nature has to deal with diverse flow fields. This takes part of responsibility for the low efficiency of robotic fish comparing with live one. In this paper, we present...
