Surveillance and monitoring has become very important for security reasons these days. Residential areas, government organizations, commercial spaces, schools and hospitals, industries, banking and other challenging indoor and outdoor environments require high end surveillance systems, which are very expensive. This paper proposes the motion detection and tracking system for surveillance in this paper...
Safety requirement is the most important issue for operators in the filed of nuclear science, especially material processing within shielded radioactive manufacturing environment under which material processing needs a great of manual operations and any operation mistake would cause to permanent radiation threat to body of operators and loss of enormous economical value. This paper proposes a novel...
Wireless technology has become a new emerging technology in stakeout and security concerns industries. Study of wireless communication with energy efficiency is also a one of the most important research area. Therefore this paper presents an efficient computerized stakeout system (CSS) for stakeout and recognition purposes with the use of energy efficient ZigBee based transceiver. The designed model...
Recently, attention has focused on the development of computer-user interfaces, which combine digital information with physical environments. In this work we have used Computer Vision as to support the concept of marrying the digital world with the physical one. This was proven by developing a novel sensing technology that allows users to use their home computer and an web camera to detect multiple...
Most image cluster algorithms group images based on the content, that can be described with some low-level image features or geometry features. In this paper, we proposed novel grouping criteria for image cluster from a aesthetic perspective. By studying the skills and techniques of professional photographers, we introduce several image features that can describe the styles of photographs. And we...
We present a method to predict collisions with objects thrown at a quadrotor using a pair of dynamic vision sensors (DVS). Due to the micro-second temporal resolution of these sensors and the sparsity of their output, the object's trajectory can be estimated with minimal latency. Unlike standard cameras that send frames at a fixed frame rate, a DVS only transmits pixel-level brightness changes (“events”)...
We created two experimental situations to elicit two affective states: frustration and delight. In the first experiment, participants were asked to recall situations while expressing either frustration or delight. The second experiment tried to elicit these states naturally with a frustrating experience and a delightful video. There were two significant differences between the acted and natural occurrences...
Agile robot locomotion on rough terrain is highly dependent on the ability to perceive the environment. In this paper, we show how the interaction between a reactive control framework and an online mapping system can significantly improve the trotting performance on irregular terrain. In particular, this new locomotion controller increases the stability of the robot and reduces frontal leg and shin...
This paper describes work on a distributed framework for collaborative multi-robot localisation and mapping with large teams of Micro Aerial Vehicles (MAVs). We demonstrate the benefits of running both image capture and frame-to-frame tracking on the same device while offloading the more computationally intensive aspects of map creation and optimization to an off-board computer. We show no impact...
The main aim of this research work is to develop means of communication for people with complete paralysis. This is done by making use of the eye movements of the patients as these patients cannot move any other body part. In this paper we discuss about two schemes a YES/NO scheme and a regular scheme. In YES or NO scheme the patient is provided with a list of amenities. One option is displayed at...
Camera calibration is a fundamental problem in computer vision community. Already extensive research has been conducted and emerge a large number of excellent calibration algorithm, but there is few studies of automatic calibration system, the camera calibration toolbox for the moment almost use multi-use manual or semi-automatic marking the target area and extracting feature points, inefficient and...
In this communication era, mobile -telephone industry has grown profoundly. The urban population uses the latest mobile-phone technology while the rural population buys second hand ones, mostly with degraded battery, that require frequent charging. This battery-problem becomes a giant when user doesnt have a standard charger or an electricity connection. In this paper, researchers intent is to propose...
Research in the field of Human-Computer Interaction (HCI) has become more and more frequently in our life. These related applications not only make our lives more convenient and efficiency, but also reduce the overhead costs. Users can more naturally, quickly and intuitively convey commands through different types of HCI applications to computer. Leap Motion1 is used to capture the information of...
The spectrum of an object moving in 5-D light field videos (also known as plenoptic videos) with constant velocity and at non-constant depth is analyzed. Based on this analysis, a novel 5-D IIR adaptive depth-velocity filter is proposed for enhancing such objects. The time-variant coefficients of the proposed 5-D IIR adaptive depth-velocity filter are derived in closed form. Numerical simulation results...
Building a high-end aerial robot for research is a challenging task. Our aim in this paper is to design a compact hexacopter capable of high payload and has flexible gimbal and powerful onboard computer with $ 500. This hexacopter serves as a flying platform with great customizability, where different sensors can be mounted easily onto the hexacopter for new applications. We discuss our implementation...
Vibrant lighting of relief maps via high-resolution dynamic projected imagery can be a powerful tool for simulation, augmented reality, and visualization, enabling several scientific, educational and entertainment applications. This is usually achieved via multiple projectors lighting the relief map, which are then sensed by multiple cameras for geometric and color calibration. However, cumbersome...
People often need help when filling out paper forms, because they do not fully understand the meaning of form fields. Commonly adopted solutions are referring to the form filling instructions or consulting other people. However, they are either inefficient or inconvenient. In this paper, we propose a situation-aware and interactive system, named Interact Form, to help people fill out paper forms....
This paper explores the control of an automobile mounted with a BlackWidow 1.0 microcontroller from a remote location using a smartphone or a computer as a data mining and analysis device as well as for the purposes of first response search and rescue during a disaster relief operation. Custom application programs; ReCon-A for the Android platform and ReCon-V for Microsoft Windows are designed specifically...
This study implements mobile-phone camera text-recognition technology into a game-based assessment design. This game is created as an alternative assessment in vocabulary instruction for learning Indonesian as a Foreign Language classroom, to explore the effectiveness and the improvement of students' vocabulary, and to increase students' motivation in conducting assessment. This game is web-based...
