In machine vision navigation, quickly and accurately recognizing the direction of curve lanes is an important step. However, many existing methods to determine directions of curve lanes have some problems with accuracy and real-time performance. Aiming to solve these two problems, this paper proposed a method based on Hough Transform to determine the curved lanes direction. Our method first recognizes...
Computer generated forces (CGFs) are autonomous or semi-autonomous actors within military, simulation based, training and analyzing applications. Rapid, realistic and adaptive behavior modeling for CGFs is imperative and challenging. Traditional modeling approaches like rule-based script usually need time-consuming, repetitive endeavor and result in rigid, predictable behavior performance. Recent...
This paper studies the typical problem of scheduling flowshop with limited storage in process industry. The optimization objective of this problem is to minimize the makespan by arranging batch size and time. Heuristic difference algorithm(HDA) is presented. The computational results show that the HDA may find optimal or suboptimal solutions in a short run time for all the instances.
During planetary imaging, the complicated imaging environment, atmospheric turbulence and the equatorial mount's inaccurate compensation for the Earth's rotation will cause image degradations including noise and deformation. A low-cost solution is image stacking which stacks low exposure frames to achieve long exposure result or averages long exposure frames to reduce noise level. The most critical...
The mining-excavation plan plays an important part in the operation management and business intelligence system construction of the mining enterprise and has great impact on decision-making of the mining enterprise. This paper takes the decision support system underground metal mine as the research object and studies its model and algorithm. Based on goals and constraints of ore blending operations,...
In this paper we propose a real-time processing technique to analyze the state of different devices located in transformer substations. More specifically, with real-time video streams provided by surveillance system, we focus on two kinds of targets—the digitron and press plate. Our approach process the input video frames with image processing algorithms such as Gaussian blur, binaryzation of grayscale...
Urban scene modeling is a promising research subject, for it plays an important role in the areas of national defense, transportation, urban planning, and entertainment industries. Researchers have been looking forward to the breakthroughs in improving the level of photorealism and the performance. This paper discusses the implementation of the simulation of certain parts of city scene. We use the...
This paper analyzes the equilibrium distribution of commuters with time-varying road pricing policy on a many-to-one mass transit system during the morning-period. In the transit system, it is assumed that commuters, which depart from different sites, choose a travel strategy with the minimum travel cost, which comprises congestion cost, the cost of travel time, schedule delay cost, fare cost, and...
The inspiration of computer design comes from the human. Learning from human cognitive mechanism, laid the foundation for the development of unmanned driving field in our country. Based on the information processing model of Cognitive Psychology, there are three stages of the manned driving behaviors "stimulus perception, judgment and decision making and stimulus performance", to establish...
A cross-corpus classification of emotional speech on two datasets, Emo-DB in German and DES in Danish is investigated in this paper. 2-D classifications on arousal-appraisal space leads to significant improvement than in one-step classifications. Emotions are better recognized in arousal dimension than in appraisal dimension. The best classification rate in the cross-corpus test is achieved on male...
In application, good OOCs have the property that each codeword has many more 0s than 1s. The code length of a conventional 1D-OOC is always large in order to achieve good bit error rate performance. However, long code sequences will occupy a large bandwidth and reduce the bandwidth utilization. 1D-OOCs also suffer from relatively small cardinality. The 2D-OOCs overcome both of these shortcomings....
In this paper, a monocular vision navigation algorithm using optical flow with Principal Direction Screen Strategy is proposed. Firstly, we present an optical flow extraction and adjusting method based on Speed-up robust features (SURF), which makes the distribution of optical flow vectors more well-distributed and increases the accuracy of optical flow. Secondly, we constructive a complete ego-motion...
