Robust feature matching using guided local outlier factor

Pattern Recognition, 2021
Abstract Matching local features on two or more images is fundamental for many applications in the field of computer vision and pattern recognition. Identifying and rejecting mismatches is an important part in the framework of feature matching, due to the putative correspondences always contaminated by mismatches with the error-prone local feature ...

Abnormal Data Detection Based on Adaptive Sliding Window and Weighted Multiscale Local Outlier Factor for Machinery Health Monitoring

IEEE transactions on industrial electronics (1982. Print), 2023
Identifying abnormal data to improve data quality is of great importance for machinery health monitoring (MHM). Existing abnormal data detection methods generally depend on appropriate parameter settings and prior knowledge of data distribution, which ...

Comparative Analysis of Elliptic Envelope, Isolation Forest, One-Class SVM, and Local Outlier Factor in Detecting Earthquakes with Status Anomaly using Outlier

2023 International Conference on Computer Science, Information Technology and Engineering (ICCoSITE), 2023
In Indonesia, large earthquakes happen frequently. Due to the location of Indonesia, over three active tectonic plates, fractures and trenches have formed on both the land and ocean floor.

Batch Process Modeling and Monitoring With Local Outlier Factor

IEEE Transactions on Control Systems Technology, 2019
Batch processes are commonly involved by a succession of working phases with implicit non-Gaussian behaviors. Besides, in most cases, batch-to-batch processes also show similar but yet not identical running trajectory variations. To deal with these issues, this paper introduces a systematic analysis flowchart based on local outlier factor (LOF) for ...
