Camera global motion estimation is critical to the success of video stabilization. This paper presents an effective and robust feature based motion estimation method. In the proposed approach, feature points are collected from input video sequences based on Speeded Up Robust Features (SURF). Random Samples Consensus (RANSAC) is used to remove local motion vectors and incorrect correspondences. In...
To classify and identify the component of abandoned shells, a design method of using ultrasonic to detect artillery shellspsila internal component based on data fusion method is presented. Firstly, ultrasonic detector is used to collect the sample data of internal component of a large number of artillery shells. Secondly, using data fusion techniques to set up neural network fusion model for data...
Based on the data samples authorized by CAIDA, we analyze the Internet router-level topology. By extracting several features of network property, we found obvious disparity distinction between the comparing results measured by single monitor point and multiple monitor points respectively, which approves that the sampling bias caused by single monitor point take primary effect on the Internet topology...
