For many existing inspection class ROV designs, a powered umbilical was the obvious choice as a means of providing system power. But advances in battery capability, coupled with the sheer diversity of applications and associated task requirements for which ROVs are now being targeted, has resulted in an interesting tradeoff between the capabilities of umbilical versus battery power. This paper will...
A quadrotor Micro Aerial Vehicle (MAV) is designed to navigate a track using neural network approach to identify the direction of the path from a stream of monocular images received from a downward-facing camera mounted on the vehicle. Current autonomous MAVs mainly employ computer vision techniques based on image processing and feature tracking for vision-based navigation tasks. It requires expensive...
Quantum Key Distribution (QKD) provides a secure way of generating shared cryptographic keys between a sender (Alice) and a receiver (Bob). The original BB84 protocol uses a two-dimensional polarization basis, limiting the information content of a single photon to 1 bit. Using the transverse position of single photons as one basis and the Fourier space as a second basis, one can construct a pair of...
There is an increasing trend for finding solutions to interact with computers, and computers in turn interact with people. For an effective human-computer intelligent interaction, this must be natural, the computer interpreting the user's emotional state to adapt to its behavior, giving an appropriate response to those emotions. This paper presents a software application for emotional states recognition...
In recent years, mobile terminals come to be used to assist works. However, we can not say that they are enough suitable to assist works either that occupy hands or that are accomplished in environment with water or fire, which cause troubles with electronic devices. In this study, in order to solve this problem, we propose an assist system using projection mapping and NUI. Note that our system is...
The SyncBoard is a reconfigurable sensor timing board that accurately records the Time of Validity (TOV) from sensors, while acting as a protocol conversion tool. It is intended to be usable by people without expertise in hardware development. To allow accurate timing, the SyncBoard has a highperformance microcontroller with a 32-bit timer clock running at a maximum of 100 MHz. By capturing the TOV...
In this paper, aiming at the problem of imprecise localization and perturbation interference in the field of traditional large screen, large screen interactive system with projection technology is designed based on the affine transformation algorithm to realize the precise interactive region coordinate positioning. Any wall touch system of human-computer interaction has been obtained by the analysis...
Although people think that their identity is not revealed on the internet, the confidentiality and protection of personal information on unreliable networks such as the internet is an important question. In this study, a sample application on network packet tracing and analysis of network cameras with Wireshark program is realized to show how partial access to personal information and location information...
This paper presents preliminary results for motion behavior analysis of Madagascar hissing cockroach biobots subject to stochastic and periodic neurostimulation pulses corresponding to randomly applied right and left turn, and move forward commands. We present our experimental setup and propose an unguided search strategy based stimulation profile designed for exploration of unknown environments....
Augmented Reality (AR) merges real and virtual objects in order to make a richer environment with additional useful virtual information. Producing AR maintenance training depends on two major points that will be Interactivity and Reusability. Recently Augmented Reality becomes the new technology revolution in software applications such as (entertainment, training, military, E-shops and games), and...
Powerful miniature single-board computers have recently gained attention, inviting computer scientists and engineers to develop various kinds of applications on these tiny devices. Having numerous benefits over full-scaled personal computers, their small size enables system mobility and allows operations under limited power resources. Exploring its computing capability, we set up a Raspberry Pi with...
In the recent years', image processing is becoming an important field in computer science. Also, interaction between human and computer is in increasing rate. Nowadays image processing used in many application for example application like measuring the distance between systems that consist of a camera and objects around the system using Stereo vision. Some previous studies use pixel by pixel search...
In this paper, we propose a jellyfish distribution management system using an UAV (unmanned aerial vehicle) and USVs (unmanned surface vehicle). The UAV was designed to satisfy the requirements for flight in ocean environment. The target jellyfish, aurelia aurita, is recognized through a convolution neural network and its distribution is calculated. A high-speed deep neural network architecture has...
This paper describes about the team SNU MACRO'S strategy for scan the code mission in Maritime RobotX Challenge. Before describing the specific algorithm for scan the code mission, our vehicle system which was developed for completing each mission for the competition is outlined briefly. To recognize the LED color of the buoy, image processing algorithm is divided into three step, including preprocessing,...
For many applications in the operation of a spherical robot, it is necessary to use optical devices to observe, track and monitor the robot's surroundings and environment. Estimating the rotation of a multiple camera system is crucial and can also be complex and computationally expensive. Demonstrating the multiple camera system with a shared central point can be simpler and require less computation...
Significant progress has been made in recent years using computer programs recognizing objects in images. Meanwhile, many cameras are embedded in battery-powered systems (such as mobile phones, wearable devices, and drones) and energy efficiency is essential. Even though many research papers have been published on the topics related to low power and image recognition, there does not exist a common...
Nowadays, the consumer reviews for various products are playing a very important role not only for consumers but also for the firms. A large collection of consumer reviews is now available on the internet. These reviews are very helpful to get quality information about the products. The consumer reviews are used as a feedback by the firms in their product development strategies and consumer relationship...
Text communication or messaging is devoid of emotional expression, gesture and intonation. As a result text communication has become a robotic conversation between human beings. People uses various applications like, Facebook Messenger, Viber, WhatsApp etc. for the purpose of messaging, where they follow the traditional system of writing messages and sending to the receivers. This paper, presents...
We grew up interacting with the physical objects around us. And there are large number of them that we use everyday. These objects are more fun to use than our computing devices. Taking about objects, another thing that get's attached with objects is gestures; how we manipulate these objects & how we use them in everyday life. These gesture are used to interact with objects as well as to interact...
Surgical navigation systems based on optical tracking technology all suffer from the requirement for an unobstructed line-of-sight. The optical path between stereo camera and tracked objects has to be kept free or the navigation is suspended. In this article, we present a new module that combines the information of two tracking cameras simultaneously, to view the surgical site from two different angles...
