With the development of online social networks, a special group of online users named organized posters (or Internet water army, Internet paid posters in some literatures) have flooded the social network communities. They are organized in groups to post with specific purposes and sometimes even confuse or mislead normal users. In this paper, we study the individual and group characteristics of organized...
Image segmentation is an important problem on image processing technique. Based on active contour model, a novel integrated active contour (IAC) model for SAR imagery segmentation has been developed. In this model, the edge information is extracted by edge detection operators based on ratio of average framework, and the region statistical information is distilled by the maximization of likelihood...
Based on the analysis of rotor imbalance mechanism, the presumption of extracting early fault features of rotor imbalance through the utilization of wavelet packet noise elimination and feature zoom as well as conducting self healing monitoring over the rotor imbalance through the utilization of electromagnetic induction principle is proposed. In addition, simulation experiment is applied to prove...
Inherent relationship between highway landscape layout-angle and landscape picture characteristics is found out after the analysis of many highway landscape pictures. The features of highway landscape layout-angle were extracted by the method of principal components analysis, and the participants marking values were clustered using fuzzy-cluster algorithm. Then a mathematics model based on support...
