The subject of this paper is a particularly challenging machine vision (MV) based sorting application where the ‘part’ is an Indian coin. The application is challenging in part because of the lack of distinctive features to differentiate between denominations as well as the variability in the features for a given denomination. Although there are coin recognition algorithms documented in the literature,...
Articulated arm robots have become critical components in the modern manufacturing environment, effectively performing a diverse range of manufacturing tasks. Robots offer flexibility through re-programmability — however, robot programming remains a time consuming task which requires highly skilled operators. Aiming to reduce the required time and complexity of robot programming, this paper presents...
The aim of this paper the extraction of human body dimensions using the latest Microsoft Kinect device. Another focus is the analysis of various application of this device in specific branches of science and research and its application in estimation of dimensions. Brief analysis of the device itself is carried out as well. The principal output of this paper the software application that utilizes...
The current paper presents the Quiz Cube application and its evaluation. The Quiz Cube application is an AR mobile learning application for students and teachers to easily make and use AR UI system using fiducial marker cubes. AR as a platform is just now reaching its full potential. Since smartphones and mobile devices are now at a sufficiently large user base, it is worth looking at the potential...
This paper presents hardware and software solution for simulation of a group of cameras used by the PLATO satellite. The simulator can be configured either to work with the scientific processing unit or as the complementary loop attitude control processing unit. Configuration and monitoring can be performed remotely, which caters to cooperatively work and guarantees traceability for quality purposes...
More and more modern technologies are used for designing clothes. One of these technologies is simulation of garments. For simulation some mechanical parameters like Youngsmodulus, Shear-modulus, bending stiffness, surface weight, coefficient of friction between fabric and skin and between like materials, and thickness are necessary and need to be determined through precise measurement. Especially...
Natural or man-made disasters often result in trapped victims under rubble piles. In such emergency response situations, Urban Search and Rescue (USaR) teams have to make quick decisions to determine the location of possible trapped humans. The fast 3D modelling of collapsed buildings using images from Unmanned Aerial Vehicles (UAVs) can significantly help the USaR operations and improve disaster...
Hydro-Québec operates 63 hydroelectric power plants and owns 668 dams, as well as 98 control structures. In order to ensure their safety and proper operation, Hydro-Québec's Research Institute (IREQ) develops robotic technologies that can perform diagnosis and intervention tasks underwater. Over the last 20 years, several generations of underwater Remotely Operated Vehicles (ROVs) have been developed...
In this paper, the DSSC safety-interlock system is introduced. It is designed to keep the DSSC mega-pixel camera in a safe-state. The system is composed of four inter-communicating sub-systems referred here as a master SIB (safety-interlock board) and three partner SIBs. Each SIB monitors and processes 75 temperature sensors mainly located in the focal plane and also distributed inside the camera-head...
Indonesia is an archipelago country with various kind of arts and cultures that must be maintained and preserved. Traditional dance is one kind of arts and cultures owned by each territory in Indonesia. Optical motion capture computer technology had been successfully implemented as traditional dance motion captured. Using this technology, traditional dancer movement could be documented and stored...
Standard endoscopy is a screening method that allows the detection of GI tract pathologies and lesions. However, it was demonstrated that endoscopy suffers from a significant miss rate for cancer detection. Therefore, there is a need to establish a standard protocol that can quantify the quality of endoscopic procedures, assist physicians in analyzing their performance and train them on how to select...
Processing of a vast number of aerial images from high-resolution digital camera always leads to the use of lengthy hours. This contradicts to the advantage of the use of UAV that could acquire and deliver the data rapidly to highlight the actual condition of the terrain. In previous studies, 1033 images were used covering the size of about seven kilometres square of the study area. During image acquisition...
Navigation is a fundamental problem that relates to localization and positioning for a humanoid robot Nao. Odometry is the one of many techniques that able to solve it. Nao humanoid robot actually doesn't have an odometry module by itself, and odometry sensors that currently available on it and can be used is only IMU module. An odometry sensor that quite interesting in recent times, usually for fusioning...
PRINTEPS (Practical INTEligent aPplicationS) is a total intelligent application development platform that integrates 5 types of sub systems (knowledge-based reasoning, speech dialog, image sensing, manipulation and machine learning). This paper shows us how PRINTEPS has been applied to classroom AI where multiple people and robots cooperate.
Presented model expands the bi-directional interface for human-computer interaction. It broadens the communication channel from a man towards a computer. This is achieved by using a digital camera devices in the HCI interface and the use of novel (taken from the literature) image analysis. Proposed interface use the full bandwidth video channel, thereby increasing the interface adaptability skills...
In this work we present our work towards the development of an ultra-fast power-based interrogation platform for its use with photonic bandgap (PBG) sensing structures. These structures are designed to have a characteristic spectral feature (a PBG edge), which will be shifted when a change of the refractive index is produced on their upper cladding. The interrogation is simply made using a filtered...
Many advanced sensors are capable of producing extremely large and continuous data streams. Hyperspectral imagers, microphones, high-resolution cameras, and 3D scanning devices can easily generate gigabytes of data per day, making it impractical for many wireless sensor platforms to stream all collected data to the cloud for analysis. Furthermore, in some sensor deployments, privacy concerns may restrict...
The paper discusses the design and implementation of a low-cost tool for analysis and design of applications involving video based networked interaction or teleoperation, such as remotely operated devices and collaborative environments. The tool is intended for providing an accurate measure of the video lag involved in the encoding and streaming video over packet networks, and for assessing the impact...
In this paper, we propose a hardware compatible queue-based image segmentation algorithm for refining initial depth maps obtained from light field cameras. In the algorithm, an array is created to record the ranges of positions and intensities of possible segments, which make following segment merging steps much more efficient. An ASIC chip based on the proposed algorithm with a plane fitting calculator...
A suite of complementary survey tools aimed at producing 1-cm resolution bathymetric models co-registered with 2-mm pixel color photography has been assembled. The design goal is to produce quantitative documentation of both geological and biological features that will allow change over time to be assessed at vertical and lateral scales approaching one centimeter. The current suite of tools combines...
