The Visual Object Tracking challenge VOT2017 is the fifth annual tracker benchmarking activity organized by VOT initiative. Results of 51 trackers are presented; many state-of-the-art published at major computer vision conferences or journals in recent years. evaluation included standard and other popular methodologies a new "real-time" experiment simulating situation where processes images as if provided continuously running sensor. Performance tested typically far exceeds baselines. source...
Material transportation is one of the most important aspects open-pit mine operations. The problem usually involves a truck dispatching system in which decisions on assignments and destinations are taken real-time. Due to its significance, several decision systems for material mining have been developed last few years, improving productivity reducing operational costs. This paper presents single-dependent agent approach based Time-dependent Markov Decision Processes (TiMDPs) model an example...
This paper presents some difficulties encountered when evaluating information obtained from infrared thermal inspections conducted in uncovered power substations. Technical, physical, and environmental factors are the main influences that have been identified. Based on field data laboratory tests, mathematical models were derived to understand load current variation influence behavior of electrical components, which suitable either extract its or forecast system under specified conditions interest.
Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder characterized primarily by social impairments that manifest in different severity levels. In recent years, many studies have explored the use of machine learning (ML) and resting-state functional magnetic resonance images (rs-fMRI) to investigate disorder. These approaches evaluate brain oxygen levels indirectly measure activity compare typical developmental subjects with ASD ones. However, none these works tried classify into...
This work presents an ensemble-based visual object tracker called KFebT. method can fuse using a Kalman Filter the result of several out-of-the box trackers or specialist methods that solve parts problem, like only estimate target scale variation. Our purpose in joining multiple is to take advantage different strengths and weaknesses each approach. The proposed fusion simple needs no training; it just output confidence measure for tracker. We performed tests on Visual Object Tracking...
With the constant development in robotics field, many solutions require a high hardware complexity to be executed resulting an expensive robotic system. Furthermore, these are usually closed box implementations that hard reproduced. Hence, this project proposes system structure reduce difficulties development. This consists of low cost robot with embedded Android phone ROS environment. For testing implementation, two phones, laptop and Arduino microcontroller have been used. The results...
Cloud computing is an area that, nowadays, has been attracting a lot of researches and expanding not only for processing data, but also robotics. robotics becoming well-known subject, it works in way to find faster manner which almost like the idea cloud computing. In this paper we have created use kind operation but, also, create framework that helps users work with ROS remote master, giving possibility several applications may run remotely. Using SpaceBrew, do worry about finding robots...
The purpose of this paper is to present a hybrid method particle filter for localization in mobile robotics. main references are the based on Kullback-Leibler divergence and self-adaptive using grid-energy. Gains drawbacks each discussed compared with developed algorithm. This explores best quality final result brings solution problem: position tracking, global kidnapping deterministic environment. work was ROS framework (Robot Operating System) tested Pioneer 3DX robot real simulation environments.
Genetic factors have been pointed out as the primary root associated with risk of autism. Recent works indicate that approximately 80% autistic people inherited condition from their parents. However, there are no estimates likelihood an parent having child. Using Hidden Markov Models, together data autism heritability, we developed a model to investigate parents generating children. Models double-layered stochastic process, and it consists nonvisible process (not observable) can be predicted...
This paper presents some difficulties encountered when evaluating information from infrared thermal inspections conducted in uncovered power substations. Procedural, technical and environmental are the main factors of influence identified. Based on field data laboratory tests, preliminary mathematical models derived, which suitable either to forecast system behavior under specified conditions or remove such components.
A model proposal to determine the influence of wind over temperature measurements when conducting outdoor infrared (IR) themographic inspections is addressed in this paper. velocity-dependent reduction factor developed and applied order estimate target absence wind, which considered as worst case. The makes use only two unknown coefficients that are determined for each application. proposed compared data available technical literature.
In this paper, we discuss the implementation and simulation results of a fault tolerant Multi-robot Task Allocation (MRTA) architecture on Robot Operating System (ROS). We have chosen ALLIANCE, tolerant, fully distributed, cooperative, behavior-based system, as architecture. first approach, system parameters were find set empirically do not systems metrics, focusing implementing task allocation algorithm. The primary contribution paper is to show benefits that ROS can bring MRTA problems...
