A Novel Approach to Detect and Classify the Defective of Missing Rail Anchors in Real-time
نویسندگان
چکیده
In this paper, we have designed a machine visionbased method to identify the defected or missed or grounded rail anchors/fasteners that attach each line with the sleepers. Rail line inspection system is executed manually, especially in third world countries, like Bangladesh. This manual inspection is lengthy, laborious and subjective. To detect and classify the damaged or missed or grounded rail anchors/fasteners in real time based on Shi Tomasi and Harris – Stephen feature detection algorithms with an accuracy of 81.25%. Besides SVM classifier is used to train the Shi Tomasi and Harris – Stephen features which helps to improve the recognition accuracy. To check the robustness of this system, it was tested against on different videos which contain damaged or missed or grounded fasteners in rail line which indicates clearly the high robustness targeted by this system. Keywords—Rail, Anchors, Shi-Tomasi, Harris, SVM

Mining Overlapping Communities in Real-world Networks Based on Extended Modularity Gain
Detecting communities plays a vital role in studying group level patterns of a social network and it can be helpful in developing several recommendation systems such as movie recommendation, book recommendation, friend recommendation and so on. Most of the community detection algorithms can detect disjoint communities only, but in the real time scenario, a node can be a member of more than one ...

متن کاملReal-Time intrusion detection alert correlation and attack scenario extraction based on the prerequisite consequence approach
Alert correlation systems attempt to discover the relations among alerts produced by one or more intrusion detection systems to determine the attack scenarios and their main motivations. In this paper a new IDS alert correlation method is proposed that can be used to detect attack scenarios in real-time. The proposed method is based on a causal approach due to the strength of causal methods in ...
