Tracking of objects in video sequences, respectively in video streaming is necessary part of video surveillance systems. Tracking and detection of objects in video sequences is very important in automobile industry as well, concretely in video based Driver Assistance System. Processing of video in real time puts high demands to methods of processing of video stream. In this paper is presented detection...
We show one can engineer the spectral correlations of photon-pairs produced in optical fibers by employing the temporal walk-off between two distinct pumps in spontaneous four-wave mixing to create completely factorable states without spectral filtering.
Automatic image registration is a basic step in multi-sensor data integration in remote sensing and photogrammetric operations such as data fusion. The effectiveness of intensity-based methods for automated multi-sensor image registration, such as Mutual Information (MI) and the Correlation Ratio (CR), have previously been demonstrated for medical and remote sensing applications. In this paper, a...
Different parts of an instance may be strong or weak indicators of the instance's label. We propose a new annotation strategy, where in addition to an instance's label, the annotator indicates parts of the instance that are rationales for its label. For two text classification tasks, we show that rationales provide a significant improvement in performance. Each instance (with or without rationales)...
The adequate modeling of correlated input processes is necessary to obtain realistic models in areas like computer or communication networks but is still a challenge in simulation modeling. In this paper we present a new class of stochastic processes which has been developed for describing correlated input processes and combines acyclic Phase-type distributions to model the marginal distribution with...
Markov arrival processes (MAPs) are used extensively in traffic modeling. Consequently a wide variety of fitting procedures have been developed. Most of these however are computationally demanding or not general enough. To resolve this problem, two-step procedures of a specific type have been made, which fit a phase-type distribution (PH) to static parameters in the first step, and extend it to a...
In this paper we propose a joint transmission scheme for LTE-CoMP using a single codeword to transmit from multiple transmission points to a single UE. Transmission with a single codeword makes the signal better aligned with the dominant eigenmode of the channel and achieves higher capacity. A design methodology of the global codebook for joint transmission from two transmission points is developed...
New High Efficiency Video Coding (HEVC) standard is designed to provide substantial coding efficiency improvement compared to H.264/AVC. Latest subjective testing shows 50% improvement has been achieved. Many new technologies contribute to the overall improvement. Intra prediction with 35 modes is one of the key improvements. Associated with that, there is a new intra mode coding method to efficiently...
In this paper, we derive the theoretical outage probability of a transmission system in the presence of source and channel correlations in the block Rayleigh fading channels, based on the Slepian-Wolf theorem. Two transmitters and one common receiver are assumed, where the correlation knowledge between the two source information streams can be expressed as a bit-flipping model. The information bits...
Advances in the mining industry could be spurred on by work in space mining technologies. This paper discusses one such synergy. The chosen space mining technology is the robotic lunar regolith excavators produced by the NASA Lunabotics Competition. Recent work explored potential terrestrial applications of such a technology, and recognized that applications requiring high flexibility and low throughput...
In this paper, we have studied some important statistical properties of error sequences of M-ary orthogonal frequency-shift keying (FSK) modulation schemes over Nakagami-m fading channels. We have derived the joint probability density function (PDF) of error sequences of arbitrary length. From the joint PDF, we have found an analytical solution for the autocorrelation function (ACF) of the error sequences...
Compressed sensing (CS) is a technique that enables sparse signal reconstruction from much fewer samples. In this paper, we propose ECG compressed sensing methods based on distributed compressed sensing to exploit the joint sparsity for both single- and multi-lead ECG signals. We apply JSM-2 (joint sparse model type 2) for jointly sparse ECG signals and formulate how to establish a partially known...
A new kind of bivariate geometric distribution is proposed, which is called as bivariate geometric distribution-type II. Then its properties are discussed systematically.
The key of the multimedia compression technique is trying to remove the correlation between the neighboring frames. Due to the computational complexity limitation, considerable correlation is still observed in the multimedia-coded sequence. This residual redundancy can be modeled as a first-order Markov model with the transition probability of the multimedia-coded parameter between adjacent frames...
Research focused in detecting cause and progression of the diseases is gathering an impressive amount of data. Integrating available information in a systemic approach requires knowledge about details as well as overview about predictable interconnections. The amount of accumulated data often underscores human mind capabilities to perceiving links and correlations. The paper offers an overview about...
Optimal route selection with reliable expected travel time has been a focus of research in transportation networks where the reliability is subject to many uncertainty factors such as traffic incidents or recurring traffic congestions. In this paper we develop an approximation method to obtain the reliability of a route travel time in a stochastic time-dependent traffic network. The proposed method...
In this paper, a new distributed joint source-channel code (DJSCC) is proposed for a communication network with multiple correlated information sources. The DJSCC is performed by puncturing the information bits of a linear block code but leaving the parity bits intact, given the fact that the correlation among the parity bits is usually much lower compared to the corresponding information bits. In...
Data glove is widely used interface device which measures hand posture (finger joint angles) and inputs it into a computer in virtual reality field. But it dose not spread throughout home because of expensive interface. On the other hand, researches to recognize a hand posture from photo/video images are performed, which are a kind of hand posture measurement system and called Vision Based Data Glove...
In cellular systems, user equipment (UE) must perform the cell search procedure in order to acquire symbol timing, frame timing, CFO, sector ID and group ID. In this paper, we introduce an improved frequency offset detection algorithm in Long Term Evolution (LTE) downlink systems. The detection algorithm including two steps, which are ML estimation and correlation detection. The ML estimation in order...
Eye contact provides a communicative link between humans, prompting joint attention. As spontaneous brain activity might have an important role in the coordination of neuronal processing within the brain, their inter-subject synchronization might occur during eye contact. To test this, we conducted simultaneous functional MRI in pairs of adults. Eye contact was maintained at baseline while the subjects...
