The unified program architecture of real time vision system (VS) with several fields of view construction is described. The offered architecture provides both onboard and stationary usage. In case of stationary usage, it provides determination of location and trajectory of objects movement in the ordered system of co-ordinates. Principles of open architecture, componential technology and use of standard...
Over the past ten years, human re-identification has received increased attention from the computer vision research community. However, for the most part, these research papers are divorced from the context of how such algorithms would be used in a real-world system. This paper describes the unique opportunity our group of academic researchers had to design and deploy a human re-identification system...
The blind spot of software testing is the assessment of the actual behavior of the system under test in the real, physical world. In this paper we show how this inherent restriction of software testing to the "cyber world" can be overcome with the use of methods and techniques from computer vision. It augments conventional software testing and allows making observations about states and...
In today's supply chain management, products are being track by many technologies including barcode and RFID. Such technologies are rigid and often prone to errors. In this paper, we will examine the reciprocated picking processes that exist within the supply chain, from manufacturing to retail chains. Utilising an array of 3D cameras, a new method to capture the user's physical interaction and gesture...
Advanced driver assistance systems (ADAS) are designed to increase driver's situational awareness and road safety by providing essential information, warning and automatic intervention to reduce the possibility/severity of an accident. Of the various types of ADAS modalities available, camera based ADAS are being widely adopted for their usefulness in varied applications, overall reliability and adaptability...
At nighttime, reduced visibility could cause foreground and background images to appear to blend together. However, ambient light is always present in the natural environment, and as a consequence, it creates some contrast in darkness. In this paper, we formulate a visual analytic method that automatically unveils the contrast of dark images (i.e. nighttime), revealing the "hidden" contents...
This paper exposes how we united computervision technology and tangible user interfaces to conceive aninnovative product targeting children audience. Voxar Puzzle isa digital game in which children have to choose a puzzle froma virtual library and assemble it by manipulating physicalblocks. Furthermore, the process used for the development ofthe game platform had innovation in mind. A Blue Oceanstrategy...
An open-source framework for real-time structured light is presented. It is called “SLStudio”, and enables real-time capture of metric depth images. The framework is modular, and extensible to support new algorithms for scene encoding/decoding, triangulation, and aquisition hardware. It is the aim that this software makes real-time 3D scene capture more widely accessible and serves as a foundation...
The topic of computer vision is of interest due to its ability to provide a great deal of information about the physical world. One problem that plagues many vision applications is that of occlusion. Occlusion is the situation where the view of an object is being blocked by one or more other objects. In this work, a multi-view approach was taken to solve the problem. The tool used was a low-cost array...
Smart cameras allow pre-processing of video data on the camera instead of sending it to a remote server for further analysis. Having a network of smart cameras allows various vision tasks to be processed in a distributed fashion. While cameras may have different tasks, we concentrate on distributed tracking in smart camera networks. This application introduces various highly interesting problems....
A new digital video-based visual monitoring system, that assists marine mammal mitigation by providing accurate, real-time sea surface distance estimation is described. Improvements on previous approaches are discussed and initial results from sea trials current taking place offshore are also presented.
The AUVSI Autonomous Surface vehicle event is a student-based competition where teams design, build and compete with fully autonomous surface vessel. These vehicles are required to preform many different tasks that vary from competition to competition but the ability to navigate channels marked by red and green markers and perform GPS based navigation is always a constant. Embry-Riddle Aeronautical...
As distributed online communication becomes increasingly common, and audiences for live online presentations grow larger, the ability to receive meaningful feedback from audience members who are distant and distributed becomes a necessity. To this end, we have built upon previous work to create a tool that is capable of providing real time feedback to an online presenter about the engagement level...
Images of folding process was collected and on-line detection of folding dislocations is explored using characteristic points in these images, which reduces the computation time. First, determine the dislocation type through characteristic points in the images of a folding process. Then, through calibration the corresponding dislocation bias for the detected type of folding dislocation can be obtained...
This article describes an innovative diagnostics and monitoring method of patient rehabilitation. It covers the description of the system, states the problems and shows a solution to them.
Wheel set wear online measurement is important for the safety running of train vehicle. Measuring principle based on structure light imaging and machine vision was put forward. The main components included structure light source, CCD and wheel detector. Calibration error of CCD and wheel detector will greatly influence the precision of the wear measurement. A calibration system was designed for the...
This paper presents a vision based cross sectional area measurement system suitable for in-process quality controlling of rubber profile extrusions via cross section measurements. The system is basically developed for solid trapezoidal shaped rubber profiles commonly used in the rubber tack manufacturing industry. Since the extrusion continuously comes out the extruder, it is impossible to view the...
The evaluation stage is an important part in the validation of ADAS robustness. Moreover, the control and the repetitiveness of the experimentations were very difficult to conduct on real road due to safety reasons. Moreover, the lack of data/sensors or the complexity of the experiment are often very penalizing for a correct and exhaustive evaluation. It is for these reasons that LIVIC launched the...
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...
Although multi-touch technology is currently a research focus in the field of Human-Computer Interaction, its relative research, however, is still comparatively few in China. In this paper, several foreign multi-touch technologies based on senor and computer vision are introduced and the advantages and disadvantages of these technologies are analyzed briefly. It is important for studying the technology...
