This paper proposed a Mixed Match SLAM embedded with two match methods, planar patch based and visual descriptor based. Planar patch based method eliminates the cost of feature extraction for motion estimation. Visual descriptor based method is more robust for wide baseline match and loop closing. We use a reasonable statistic criterion to determine keyframe for redundancy avoidance. An efficient...
Link prediction is a basic problem in the research of social networks. At present, most link prediction algorithms are based on the features extracted from network structure, few research concerns the effect of natural attributes of nodes for creating a link. In this paper we develop a novel way to predict links based on Random Walk algorithm using the information from both the network topology and...
A novel dehydration device was put forward to reduce the mist content in blast furnace gas. Aiming at the complex two-phase flow of curved-plate dehydration equipment, its capabilities were studied by changing the structures and operation parameters. The effects of all the factors on dehydration efficiency and pressure loss were also discussed. The results indicate that the optimum gas velocity is...
High-frequency stress wave analysis was used as characteristic parameter to detect the early stages of the loss of mechanical integrity in low-speed machinery in the paper. The background noise was eliminated using wavelet decomposition and the feature frequency of fault stress waves was extracted. Firstly, according to the characters of the fault stress waves obtained from a steel mill, db6 was selected...
According to the deficiency of the traditional detecting method, this paper develops a set of intelligent automatically detecting system for the internal bore surface quality, which combined the image processing technology and pattern recognizing technology. The radius of image is detected using Least-squares fitting circle theory and circular degree is obtained through calculating circular surface...
